I work in Medina Ohio and one of My Marines found this bug and we would like to know what it is?? It is about 4 inchs long thank for any help you can give.
SSgt Horton USMC

Dear SSgt Horton,
Your Marines have captured a female Ichneumon Wasp (Meharhyssa species). That long “stinger” is in fact her ovipositor, and she locates wood boring grubs inside trees with her acute hearing, and penetrates the wood with the ovipositor, depositing an egg near the living grub. The egg hatches and has a living dinner, feasting on the grub until the grub dies from the parasite. We have additional information in our Buggy Biography section as well as on the wasp page of www.whatsthatbug.com. Thank you for the great photo.

Letter 1 – Ichneumon species


I found an insect living with me a couple of days ago in my California condo which is nestled against a small, grassy hill. At first, I avoided it – I am very afraid of insects, but I have no desire to harm them. Then I became more and more curious because I’ve never seen anything like it before. It looks like a fly’s torso put onto an orange, wasp-like body! It’s about 1 inch long. I overcame my fear enough to trap it and take a few photos for you. What is it?
Best regards,
Lyndie Chiou

Hi Lyndie,
The reason your Ichneumon looks like a wasp is because they are related, though Ichneumons do not sting. What looks like a stinger is in fact the ovipositor, the egg laying organ of the female Ichneumon. She uses the ovipositor to deposit eggs inside the bodies of her host insects, often caterpillars, and the young Ichneumon will eat the prey alive from the inside. Ichneumons are important in the biological control of insect pests, so they are beneficial.

Letter 2 – Unknown Wasp in Washington State is Ichneumon species


YellowJacket/Paper Wasp or something else?
Thanks for the Reply. We live in Mill Creek, just south of Everett, Western Washington State. We have a bunch of these (20+) flying low all around our front yard. My best guess would be a Paper Wasp or Yellow Jacket, but the coloring doesn’t match any of the pictures I found. Just wondering if we need to have someone come out and take care of them. We’ve check the closest tree and the house eves and don’t see any nests. They don’t seem to go into the back yard, or the neighbors front yard. They are not aggressive at all. They don’t seem to care if we are walking through the yard or not.. Thanks Again..

hi Stephen,
Thanks for writing back so quickly and providing a location. That is so critical with many identifications. We can tell you that this is NOT a yellow jacket nor a paper wasp, but we are not exactly sure what it is and it will require some research. Meanwhile, we will also contact Eric Eaton for identification assistance.

The wasp is an ichneumon wasp, family Ichneumonidae. Pretty much impossible to give a more specific identification without having the actual specimen to look at under a microscope. As larvae, alll ichneumons are parasitic on other insects (spiders in a few cases).

Dear No,
This is a parasitoid Ichneumon Wasp and there are several pictured on Nature Spot that look similar including
Buathra laborator which is described on Nature Spot as being “Quite a large blackish insect with mainly orange legs. There are other similar species and expert help is needed with identification. ”  Also similar looking is Pimpla rufipes which is described on Nature Spot as being:  “Length about 15 mm. A mainly black species, but with bright orange legs, the hind pair of legs being only slightly larger than the other pairs. The ovipositor of the female is quite thick and short and the ‘waist’ between the thorax and abdomen is also quite short” and “Mainly an autumn species.”

Hi Jana,
This is an Ichneumon, member of a group of Parasitic Wasps that prey upon Arthropods.  Many species of Ichneumons are very host specific, often preying upon a single species of Lepidoptera, Hemiptera or even one of the Arachnids.  Identifying the exact species of Ichneumon in the large and confusing family Ichneumonidae is a daunting task, but if you want to pursue that route, the Landcare Research site for New Zealand might be a good point of departure.

Dear Curious’s Mom,
This is some species of Ichneumon, a group of parasitoid wasps that prey upon other insects and arthropods.  The “stinger” is actually an ovipositor, and many Ichnuemons use the ovipositor to deposit eggs beneath the surface of stumps and logs that are infested with wood boring insects.  Those Ichneumons are commonly called Stump Stabbers.  We don’t get many submissions from Alaska, and we try to identify creatures to the species level whenever possible, but Ichneumons are a large group of insects and many species are not well described.  Your Ichneumon appears to be a very different species from this previous Ichneumon from Alaska that we posted several years ago.  Your individual does look very similar to this member of the genus Rhyssa that is posted to BugGuide.

Signature: Jamie



Dear Jamie,
This is a Parasitic Wasp known as an Ichneumon, and for many years we claimed that Ichneumons did not sting.  What you have taken for a stinger is actually the ovipositor of the female Ichneumon.  We later learned that some Ichneumons are capable of stinging humans, but they are a rarity among the large number of members in the family.  According to BugGuide:  “arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates.”  As a side note, the stinger in bees and wasps is a modified ovipositor that has adapted to multitasking:  laying eggs as well as stinging potential threats.

Dear Daniel,
Thank you for the identification, and it’s good to know it’s unlikely to have stung me since it wasn’t that big! (I let it go later as well, so now I don’t have to feel too bad about letting a potentially harmful insect go around my place.) Also, huh, I always thought the stinger for bees/wasps was specifically for stinging. The more you know…!
Thanks again so much!

Hi Jamie,
We should clarify one matter regarding the stingers of Bees and Wasps.  Generally, social species have a queen and workers with the workers being sterile females.  The stingers of the sterile, social workers, including Honey Bees and Hornets, only serves as a stinger.  In those cases, the modification that has evolved is no longer capable of multitasking.

Hi Chris,
This is a Parasitoid Wasp known as an Ichneumon.  The closest match on the Bugs and Weeds website is identified as
Ichneumon suspiciosus agg. and this is the information that is provided:  “Like many Ichneumon species, this is a member of an aggregate group of very similar looking species (hence the ‘agg.’ suffix) that cannot be definitively identified without recourse to close microscopic scrutiny.  The yellow and black banded antennae and legs and an overall length of 15mm (excluding antennae) suggests that it might possibly be Ich. suspiciosus – or something similar!  It is an endoparasite of moth larvae. That is, the adult female ichneumon inserts an egg under the skin of a caterpillar and the resultant wasp larva will slowly develop internally within the caterpillar until the caterpillar enters pupation. The parasite will then enter its own pupation and, on completion of its metamorphosis, will be the sole adult insect to emerge.  This will take place in summer or autumn and the emergent adult will hibernate throughout the winter to fly again in spring coincident with the emegence of adult moths and the next generation of their caterpillars.”  UK Safari also has a photo.  Your individual is black and white, but it looks very similar.  We suspect it is a closely related species.  It should be noted that Ichneumons can be very difficult to accurately identify to the species level.  The ISpot website has a very close match that is not identified.

Hi Bugman!
I just want to start off by saying that I LOVE this site. It’s so helpful in identifying bugs all over the place. This morning, I found this bug sitting on a wall, and I have to say, he scared the pants off of me! Any idea what kind it is? At first glance I thought roach, then I looked at it a little closer, and thought, maybe it’s some weird mosquito or wasp that I haven’t seen before. I live in Alpharetta, Georgia… about 40 minutes south of the north Georgia Mountains, just to give a range for this bug. Any help identifying him would be appreciated! Thanks!

Hi Vikki,
This is an Ichneumon, and it is a wasp. Ichneumons are parasitic on other insects, most often wood boring insects, and the female lays eggs with a long ovipositor. Most Ichneumons do not sting, but we have heard from Eric Eaton that some species can sting.

Thanks so much for letting me know! 🙂 I really do appreciate all your hard work with the site and keeping up with the billions of requests you get. 🙂

Signature: Tom



Dear Tom,
This is a parasitic wasp, most likely an Ichneumon, and though it is quite frightening, Ichneumons are not aggressive and they do not attempt to sting humans.  What appears to be a stinger is actually an ovipositor, an organ that has evolved so that the female can deposit her eggs where they will hatch and the developing larva will have access to a food supply.  Your individual resembles the North American Stump Stabbers in the genus
Megarhyssa, and the female wasp uses her ovipositor to deposit eggs in stumps and branches that are infested with wood boring larvae of Wood Wasps known as Pigeon Horntails as the larvae of the Pigeon Horntail is the sole food of the larvae of the Stump Stabber.  Your Ichneumon looks very similar to this Perithous species that is pictured on FlickR.  Alas, the folks who post to FlickR never seem to provide a location for their images.

Letter 11 – Gasteruptiidae Wasp, not Ichneumon


Hi Daniel and Lisa,
When I first saw this flying critter, I thought that it was a pelecinid. After doing some research, I’m not very convinced that this is what this is. It was maybe a 1 inch to an inch and half from head to the end of its ovipositor. I’m guessing that it’s an ovipositor and not a stinger. had rescued it from my pool, and was able to get some shots of it while it dried its wings. Any info or direction you can give me in identifying this insect is very appreciated. Thanks!

Five-eyed wasp?

Hi Bug People!
On my weekend hike in the nothwestern Negev desert, Israel, I came across this wasp. I don’t even know where to start looking for information on it. It wasn’t very active and let me take close ups.
Later, when I looked at the pictures, I noticed three extra ‘eyes’ on its head. Any ideas that might point me in the right direction would be appreciated!
It was about 2.5cm (1 inch) long, dull orange, with very long antennae. I saw no ovipositor so I’m guessing it’s a male.

Hi again Ben,
WE are relatively certain this is an Ichneumon, a family of parasitory wasps that is nearly impossible to identify to the species or even genus level without inspection of the actual specimen by an expert. Many wasps have three simple ocelli in addition to two compound eyes.

Letter 16 – Black Swallowtail Caterpillar Metamorphoses into Chrysalis: Ichneumon Emerges!!!


this was supposed to be a black swallowtail butterfly
Location:  southwest ohio
August 11, 2010 4:19 pm
i found a black swallowtail caterpillar,

Black Swallowtail Caterpillar: Beginning Metamorphosis

(found that on your site) in my front yard. a few days later it put itself in a cacoon or chrysalis. yesterday i noticed something flying in the container but it was way to small to be my butterfly. WHAT IS THIS??????????

Black Swallowtail Chrysalis

By all outward appearances, your Black Swallowtail had begun its metamorphosis into a chrysalis and things should have culminated in the emergence of a butterfly, but while it was still a caterpillar, your individual was parasitized by a type of wasp known as an Ichneumon.  We quickly identified the adult Ichneumon that you photographed as
Trogus pennator, which BugGuide indicates “is a parasitoid of swallowtail butterflies (Papilionidae), ovipositing in the caterpillars. The female Ichneumon lays a solitary egg inside the caterpillar using her stingerlike ovipositor.  BugGuide has a nice series of images documenting this process. The Ichneumon Larva develops inside the the caterpillar, feeding upon its internal organs and allowing it to pupate into a chrysalis.  At some point hidden from view, the Ichneumon Larva undergoes its own metamorphosis into a pupa, eventually emerging as an adult wasp and chewing its way out of the chrysalis through an irregular hole.  The adult butterfly will not emerge once it has been parasitized.  BugGuide also has a photo that illustrates that action.  Back in the seventeenth century in Germany, artist and naturalist Maria Sibylla Merian became one of the first people to notice and document insect metamorphosis at a time when the accepted theory was spontaneous generation.  Maria Sibylla Merian observed that caterpillars formed pupae and emerged as moths and butterflies as part of a natural process of metamorphosis, but she was puzzled that some caterpillars did not metamorphose in a typical manner, emerging instead as flies or wasps.  She documented this puzzle in her intricate drawings which were published in a two volume book known as Caterpillars, Their Wondrous Transformation and Peculiar Nourishment from Flowers or simply The Caterpillar Book.  You should be able to see the hole in the chrysalis.  As a point of clarification, butterflies do not form a cocoon as their pupae are bare.  A cocoon is usually spun of silk to cover a naked pupa.  Most moths form a cocoon to protect the pupa.

I’ve seen these things every now and then, but I’ve never been able to find an image(or identification for that matter) of them online.
The ”capsule” was hanging from a thread about an inch long that was fastened to the underside of a privet leaf. It reminds me of a lacewing’s egg, but I’ve never seen one this color, and image searches proved to be useless as well. I figure that it could possibly be some sort of chrysalis, but it’s rather small and seems to be fairly smooth.
Any ID or some pointers leading to an ID is greatly appreciated. I love checking in on the site every day or two to see what’s new.

Ichneumon Cocoon

Hi Jacob,
We opened your photo and letter the other day, and we were pressed for time and we didn’t know where to begin with your identification.  Today, we were trying to identify an Ichneumon image that was sent to us and we stumbled across this posting on BugGuide that is identified as the Cocoon of an Ichneumon in the subfamily Campopleginae.  Bingo, that was your cocoon.  Please excuse the late response.  We identified this mystery quite by accident and then we had to go through old mail to locate your letter.  Luckily the subject line was memorable.  Here is the comment Charley Elseman posted to BugGuide:  “One of many subfamilies of ichneumonids. Most other ichneumonids form cocoons within their hosts, or at least within their hosts’ cocoons, and as far as I know none have fancy patterns like this. I think that many different campoplegines make cocoons with a pattern reminiscent of this one, but only a few suspend them from a string like this. Bob Carlson may be able to say something more specific about it.
”  Bob Patterson wrote this comment:  “See the page on Parasites, Predators and Parasitoids at MPG. There is no doubt equivalent and even better material to be found here at BugGuide.

Thanks for the identification! That link to BugGuide helped ID some of the little wasps that have been sneaking around the house lately on top of helping to ID the cocoon.

Hi Sara and Jacob,
This is an Ichneumon. Ichnuemons are nonstinging relatives of wasps. The female uses her long ovipositor to deposit eggs into the host insect. Many Ichneumons parasitize wood boring insects, hence her presence in a wood pile. Our guess is that this is a species of Arotes.

Dear Apartment Dweller,
This is an Ichneumon.  Ichneumons are a group of parasitic wasps that prey upon different insects.  This may be a male Ichneumon which would explain the lack of a stinger.  Many female Ichneumons, especially in the genus Megarhyssa,  have highly developed ovipositors, some up to five inches long.  These organs are needed to locate wood burrowing larvae that serve as food for the young.  Other Ichneumons have much smaller ovipositors.  This is a large confusing group of insects, and we rarely attempt to make specific species or genus identification attempts.

Hi Steiv,
This is an Ichneumon Wasp, and we believe we have identified it as Messatoporus discoidalis on BugGuide, though Ichneumons are notoriously difficult to identify.  Ichneumons are parasitoid wasps, and according to BugGuide, depending upon the species, their prey includes:  “a great variety of hosts (mostly immature stages) is used, though most species attack only a few host types; some infest spiders and other non-insect arthropods.
”  If our identification is correct, your Ichneumon is in the tribe Cryptini, and according to BugGuide:  “Cryptini search for hosts primarily among foliage (rather than in the soil or ground litter) and have larger average size.

Signature: Catharine


Dear Catharine,
This is a species of parasitic Wasp in the family Ichneumonidae, a large family whose members are known as Ichnuemons or Ichneumon Wasps.  The female is identified by her long ovipositor, an organ that has been adapted into a stinger in many species of bees and wasps, though most species of Ichneumons are not capable of stinging humans.  The ovipositor in Ichneumons is used to deposit eggs in or near the bodies of the host prey for the larva, and in the case of the Stump Stabbers that have an ovipositor as long as five inches, this involves drilling into dead and dying wood to locate the wood boring larvae of Wood Wasps, their sole host.  Ichneumons can be very difficult to identify to the species level, but we believe your species might be
Coleocentrus rufus which we found on BugGuide.  The genus page for Coleocentrus rufus on BugGuide states:  “hosts unknown for most NA spp. (a lepturine reported for C. flavipes),” and that may mean that the host for your species is also a wood boring beetle larva in the Longhorned Borer family Cerambycidae, subfamily Lepturinae.

  According to BugGuide, there are:  “About 5,000 described species in North America, possibly 3,000 more undescribed(2); arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates(3)).”

Hello bugman! I have these annoying, non-aggressive wasp type bugs all over our property. I usually only find them at night, except for the occasional one that sneaks inside. I caught one the other day and he tried continuously to sting the paper towel, with what resembled a small stinger on his back end. They aren’t aggressive, they seem very unintelligent, and they are very thin in that there isn’t much matter to them. They are a reddish brown see-through color, with clear wings outlined in the same body color. I’ve found several different sizes of them as well. I’ve never seen or heard of a wasp being active at night, so I’m baffled as to what this could be! Southern NJ just outside Philadelphia, warm days(60-70º), cool spring nights(50-60º). Started noticing them last year around this time, lasting through the summer and warmer months of Fall. Any info you could give would be GREATLY APPRECIATED! Thank you 🙂 (this picture i s zoomed in very close)

Dear Annoyed in NJ,
This is some species of Ichneumon, a member of a very large family of parasitic wasps.  Some species are attracted to lights at night.  See BugGuide for additional information on this family including this tidbit of information:  “About 5,000 described species in North America, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates).” 

Thank you so much for the information and quick response!  I look forward to learning more about these little buggers!

Can you help me identify this skyscraper bug???
I spotted this interesting bug on the outside of a window on the 39th floor of a skyscraper in downtown Chicago. Is it an Ichneumon? It was not very large, maybe and inch and a half in length (including the stinger/ovipositer). I can’t seem to find out exactly what it is, and the fact that it was so high up on the building has me stumped. I see spiders in abundance outside the windows at certain times of the year, but never anything like this.

Wow Nicole,
This is the best photo we have received in a long long time. Yes, it is an Ichnuemon.

Hi BB,
This parasitic Ichneumon Wasp is in the subfamily Ophioninae and you may read more about them on BugGuide.  This is one group that is frequently attracted to lights, and though we generally inform our readers that Ichneumons are harmless, we learned several years ago that this group is known to sting.  According to BugGuide:  “Females have a very compressed abdomen and a short, very sharp ovipositor. The ovipositor can penetrate the human skin; most other ichneumons can’t ‘sting’.”

Hi Devin,
This is a parasitic wasp known as an Ichneumon.  For many years we thought that Ichneumons were incapable of stinging humans, but we later learned that one particular group of Ichneumons in the genus
Ophion can sting.  According to Nature.com:  “while Ophion is one of the few Ichneumonidæ which are known to sting, and while a small, narrow poison sac has been detected in a few species of that immense family, none has been recorded in Ophion luteus. But whereas the sting is followed in every instance by considerable inflammation and pain, such as would not be the effect of the mere stab of a needle, it seems almost certain that some irritant is injected into the wound, possibly for the purpose of paralysing the fly’s legitimate victim, as in the case of the hunting-wasps.”  According to BugGuide:  “They are often attracted to artificial lights.”  We believe your Ichneumon is in the genus Ophion.  We have tried unsuccessfully to convince folks that Crane Flies do NOT sting, and we believe they have been mistaking these Ichneumons for Crane Flies.

Female Stump Stabber, missing her ovipositor

Dear Mike from Philly,
We can tell you that this is a parasitic Ichneumon Wasp, but we are having trouble conclusively identifying it to the species level, so we have contacted Eric Eaton and explained out doubts.  The yellow antennae and shape of the abdomen rule out a male
Megarhyssa atrata which is pictured on BugGuide and Beetles in the Bush, and all the examples of  Therion morio on BugGuide have black heads.  What this Ichneumon looks most like to us is a female Stump Stabber, Megarhyssa atrata, but with a missing ovipositor, a condition we could not really explain.  See this BugGuide image for comparison.  We will get back to you when we hear from Eric Eaton.


Maimed Female Stump Stabber

Definitely agree with you that it closely resembles the female stump stabbed after doing a little more research on the Internet.  But why no ovipositor? Can it become disconnected when/after laying its eggs? Could a bird have eaten just that part of it? Hopefully Mr.  Eaton has an idea.
Thank you so much for responding to me.  Can’t wait to tell my son.  Keep me posted.

Eric Eaton Confirms our suspicions
This is a *female* M. atrata that has lost her ovipositor.  Sometimes they get “stuck” while in operation, and/or the wasp needed to flee a potential predator.  I have frequently found ovipositors lodged in logs or stumps, the wasp having been consumed by a predator while in the act of laying eggs.

Thanks for the confirmation Eric.
I have heard that sometimes the females get stuck while ovipositing and cannot withdraw, dying in the act.  Is that also true?

Horntail? (Kirkland, WA)
I have two, sometimes three of these, everyday, on the south facing windows. On the inside. Have not seen these insects around the home in previous years, but two events may explain (aside from the season). The first is the neighbor’s house was destrpyed by fire, the second I have had the torch down roof replaced. Now some of these insects I see each day have an ovipositor and some like this one pictured, don’t. And then again, some have an orange banding around their bodies and not yellow … and there appears to be an armored shell. The picture was taken using a Nikon Coolpix 775. The insect is in a glass jar. Wasps or horntails?

Hi chrisE,
This appears to be a male Ichneumon. Females have the long ovipositors. Eggs are laid deep inside dead and dying trees since the larval food is wood boring insects. Ichneumons are related to wasps. Eric Eaton added the following: ” Oh, that male ichneumon could be a female. Not all female ichneumons have a long ovipositor. In fact, most don’t.”

Hello Mr Bugman Sir,
I know you are busy what with this being summer but curiousity about this guy (girl?) is just too much to take!!! Seriously I am attempting to ID it myself and instead have made myself aware of way too many spooky creatures out there! Please pretty please look at my picture! Ok enough begging. Although his coloring is a bit drab now, when alive his legs were bright crimson and the body parts were a shimmery bright blue. He has two long curling (Suess-like) antennae and two stingers? trailing from the back end. These started flying during May sometime into our house in Victoria, B.C. ‘Course I am hoping that they are termites or carpenter ants – they don’t fit the description from what I can determine. Please tell me they are something innocuous and just plain pretty, made by Mother Nature.
Thanks, in advance, for your consideration.

weird flying orange antennae big bug in Canada
Hi. Awesome website!
I checked through and can’t find this weird flying bug with a black body (that it holds flipped up, over its head – although the 2nd pic I did get in normal position), and orange antennae. I’m always photographing butterflies and bugs and love their beauty, however I have to admit this ‘thing’ scared me! It’s about 2-3 inches long, and I had never before seen it in southern Saskatchewan, Canada. Many thanks

Hi Fran,
We thought this was a male Ichneumon in the genus Megarhyssa, but we were wrong. See Below.

Many thanks. If it’s any help: when my sister and I first spotted it: it looked like it had just wings and antennae, like it was trying to stuff its body into the crack in the tree. (weird). Then it had it flipped over its back most of the time, and only for one ‘wiggle’ did it appear normal, then back to this position. Looking forward to your reply. Best regards,

Correction: (07/31/2007)
Eric Eaton set us straight. Here is what he wrote: “Hi, Daniel: That is an ichneumon wasp, but NOT a Megarhyssa. We have images over at Bugguide identified as Gnamptopelta obsidianator, but I don’t know any more than that. Females of that species lack the long ovipositors.

What’s THIS bug?
Hi there,
This bug appeared on my desk tonight and we’ve never seen one like this before. What made me take notice of it most was the white midsection on the dark coloured antennae. I apologize for the quality of the photos but our digital camera won’t take good closeups. This is the best I could do. One photo was taken while the bug was sitting on a white envelope and the other two were taken with it sitting on the beige wallpaper. The bug is about an inch long if you count in the antennae. He flies from one light to another or sits on the wall next to the light. I’d appreciate knowing what it is. I looked on your website but, not knowing what type of bug to look up, I’d have to look at every listing there. Since I have dialup and not high speed, that would take forever. Thanks in advance for any help you can give me. I hope this thing doesn’t bite because we’ve chosen to let him fly free. If he lands on me, I may change my mind on that though!

Hi Cheryl,
This is an Ichneumon. Ichneumons are an important group of insects that parasitize caterpillars, wood boring insects, aphids and others. Ichneumons are related to wasps, but they do not sting. BugGuide has identified your group of Ichneumons in a very general sense according to color: Black/White w Orange legs, Dot on Back, White on Antennae. BugGuide also indicates that Ichneumonidae is: “One of the largest families of insects with over 3100 species in North America (60,000 worldwide). The majority resemble slender wasps. They differ from the wasps that sting (Scolioidea, Vespoidea and Sphecoidea) in that they have the antennae longer and with more segments usually 16 or more). In many ichneumons the ovipositor is quite long, often longer than the body. It is divided into 24 or 35 subfamilies depending on different authors.. Many Ichneumons are of value in the control of noxious insects. “

The look on your face is quite startled.  This is some species of Ichneumon, a family of Parasitoid Wasps that are not aggressive, though we have occasionally gotten reports from folks who have been stung.  Female Ichneumons lay eggs on or near specific insect or arthropod hosts and the larval Ichneumon feeds on the host insect, eventually killing it.  We are unable to determine the species of Ichneumon that entered your friend’s home.  According to BugGuide, the family Ichneumonidae:  “About 5,000 described species in North America, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates).”

I don’t want to overload you guys with questions, so I hope this second bug in as many days isn’t too much.

I tried searching for it on the ’Down Under’ tag, but it doesn’t seem to exist in the first 60 pages.
The females of this insect seem to have massive ovipositors, but that’s about all I know of them, besides a happy affinity to spend all day flying hopelessly against glass windows.
Even if you don’t get around to looking at this, thanks very much for the site — you’ve done a great job with it.

Hi Tasha,
This appears to us to be an Ichneumon, a type of Parasitic Wasp.  Sorry, no time right not for additional research.

Thank you for your fast response. If you do have time at a later point, I would be very interested to know what it’s parasitic to. Otherwise, thank you very much for your time, and I hope things go well for you!

Hi again Tasha,
Without knowing the species of Ichneumon, it would be impossible to determine the host.  According to the North American website BugGuide, they feed upon:  “a great variety of hosts (mostly immature stages) is used, though most species attack only a few host types; some infest spiders and other non-insect arthropods.”
  Some common host insects include caterpillars, beetles and the larvae of wood boring wasps.

Thank you again,
Now that I know what to look for, I think it’s the Orange Caterpillar Parasite — Netelia Producta. It seems most prevalent in Queensland (which is probably why trawling for ‘orange wasp Victoria’ didn’t help), but it appears it can come this far south, after I found record of a few sightings of it in Melbourne.

Dear Bugman,
I’ve just been visited by one of the most beautiful insects I have ever seen and wanted to ask you if you could identify my nightly guest?
One strange thing I noticed is it had what seemed like three extra eyes on the top of its head right between the two big eyes, on the base of its antennas.
A pretty exciting sight, I don’t see such exotic looking insects around here very often.
Greetings from Austria,

Hi Michael,
We really enjoy getting requests from people who think insects are beautiful that other folks might find repulsive.  This Ichneumon is a parasitic wasp that preys upon other insects and arthropods.  The female lays her eggs within the host by using an ovipositor.  Some wasps have evolved so that the ovipositor has adapted into a stinger and many Ichneumons have very long ovipositors.  A group of North American Ichneumons in the genus
Megarhyssa can have ovipositors as long as five inches in length and they are known as Stump Stabbers since the female uses her ovipositor to lay her eggs in wood that is infested with wood boring insects.

I found this pretty bug flying around my bush and I don’t recall ever seeing one before. It’s purplish wings were really pretty in the sunlight. Could you please identify it for me?

Ichneumon: Trogus pennator

Dear Caitlin,
The long antennae on this magnificent wasp caused us to correctly speculate it must be an Ichneumon, and we quickly identified it on BugGuide as
Trogus pennator.  According to BugGuide:  “Trogus pennator is a parasitoid of swallowtail butterflies (Papilionidae), ovipositing in the caterpillars.  The solitary larva develops inside the caterpillar, allowing it to pupate before killing it. After metamorphosing, the adult wasp chews an irregular hole in the chrysalis to escape.”

Dear Tracey,
Those antennae lead us to believe that this is some species of Ichneumon, a family of parasitoid Wasps whose larvae feed on the internal organs of host-specific Arachnids and immature insects including Caterpillars, Beetle grubs and larvae of wood boring Wasps.  This is an enormous family with according to BugGuide:  “~5,000 described spp. in almost 500 genera in the Nearctic Region, possibly 3,000 more undescribed.”  We doubt it is your species because it is not reported as far north or west, but your individual does resemble 
Limonethe maurator which is pictured on BugGuide.

Dear JPB,
This is an Ichneumon Wasp, but our initial search did not turn up any matching images online.  Ichneumons are a large family of wasps that are parasitic on other arthropods, and each species of Ichneumon is generally very specific about its prey.  Ichneumons can be very difficult to identify to the species level.  Though this is not your species, you might enjoy reading this account on the Sutton Park Natural History website.

I found this bug in my bathroom today and thought it was just so pretty! I wish i just knew what it was… any ideas?

Dear tegan xx,
This is an Ichneumon, a type of parasitic wasp.  Many species are attracted to lights, which is why we suspect it was found in your bathroom.  Your individual reminds us of
Ophion obscuratus which is pictured on iSpot.

Letter 63 – Ichneumon from New Zealand


Hi Bug Man,
We found this wasp like insect today. We have never seen anything like it. Hope you can tell us something about it. The first photo is taken up against a yellow lighter that is 8cm long. Looking forward to hearing from you. Many thanks and best wishes,
Tina Chambers

Hi Tina,
This is a species of Ichneumon. Ichneumons are parasitic wasps. Many lay eggs deep inside wood where the host wood-boring insects live.

This is a parasitoid Ichneumon and it looks similar to
Ophion luteus which is pictured on Wildscreen Arkive.  We are postdating your submission to go live to our site later in the month while we are away from the office for the holidays.

Letter 65 – Ichneumon from Scotland


wasp photo
Hi there
I have been through your wood wasp shots but couldn’t find anything like this one. My parents found it beside their pile of firewood logs. It is about an inch long (2.5cm) and the ovipositor is a bit longer than the body. We have never seen anything like it. Some of the logs had 4mm bore holes in them.

Hi Peter,
Ichneumons are wasp relatives, but have their own page on our site. This looks very similar to our American Megarhyssa species, but we cannot conclusively say that is the correct genus without more research. Female oviposits deep in rotting wood where larvae feed on wood boring insects.

I found this wee creature hanging on the wall in my workplace, a bingo club. I’ve never seen anything like it at work, I don’t think I’ve seen anything like it at all! Can you help me and my colleagues find out what it is?
Many thanks,
Signature: Any way you’d like.


Dear Any way you’d like,
This is an Ichneumon parasitoid wasp.
  According to the Cornell University Department of Entomology Biological Control website:  “Insect parasitoids have an immature life stage that develops on or within a single insect host, ultimately killing the host, hence the value of parasitoids as natural enemies. Adult parasitoids are free-living and may be predaceous. Parasitoids are often called parasites, but the term parasitoid is more technically correct. Most beneficial insect parasitoids are wasps or flies, although some rove beetles (see Predators) and other insects may have life stages that are parasitoids.  Most insect parasitoids only attack a particular life stage of one or several related species. The immature parasitoid develops on or within a pest, feeding on body fluids and organs, eventually leaving the host to pupate or emerging as an adult. The life cycle of the pest and parasitoid can coincide, or that of the pest may be altered by the parasitoid to accommodate its development.  The life cycle and reproductive habits of beneficial parasitoids can be complex. In some species, only one parasitoid will develop in or on each pest while, in others, hundreds of young larvae may develop within the pest host. Overwintering habits may also vary. Female parasitoids may also kill many pests by direct feeding on the pest eggs and immatures.”

Ichneumon might be Amblyteles armatorius

This is not a Hornet, but it is a Parasitoid Wasp known as an Ichneumon.  There are so many species that look similar, an exact species identification might not be possible, but it does resemble Amblyteles armatorius which is pictured on UK Safari where it states:  “Ichneumon wasps are solitary insects which are closely related to bees and ants. Most ichneumons are parasitoids.  The females lay their eggs into, or onto, the young of other insects and spiders, and the young which hatch out feed on that host insect.  The host is eventually killed and consumed by the larva just before it pupates.”  There are additional images on Nature Spot.

  1. Lisa says:

    I have an issue that I hope you can help me with. I have a large maple tree (seemingly healthy) that is being visited by the Ichneumon Wasp. There are many holes in the base of the trunk (about two – three feet from the base) which is the apparently the result of the adult cutting a circular exit hole when it leaves the tree. The information I[‘ve found indicates that the Ichneumon Wasp is not considered a serious pest since attacks are limited to trees or individual limbs that are in serious decline or very recently dead. Again, my tree does not show any obvious signs of disease nor does is show any signs of dying.
    My questions are:
    (1) Once the larvae become full grown what type of damage do they do once they exit the trunk and how can I prevent it?
    (2) What type of damage have they caused inside the trunk of the tree and is this repairable?
    I don’t want to loose this tree so am hoping that you can help. Thank you.

    • bugman says:

      hi Lisa,
      The Giant Ichneumon is a parasitic predator. The larvae parasitize wood boring insects like the Pigeon Horntail. The Giant Ichneumon is not a problem, but its presence is symptomatic of another potentially harmful insect boring in the wood.

  2. Lisa says:

    The only other insect that I have seen on the tree looks like a potato bug (sow bug). I[‘ve read that they are not a serious threat either as they do not damage the wood. Could this be what the Ichneumon Wasp is feeding on?

  3. somedude76 says:

    We found some of these in our yard too. They seem to be about 20 of them flying around our garden. They show up in the morning and are active until just before dusk.

    They are not aggressive at all.

    Any information on habitat or nesting that you could share? Do they live in a colony that I could exterminate? Just curious. I’ll probably just leave them be since they aren’t aggressive. I do worry some though since we have a four year old. Don’t want her to get stung.

    • Joseph M Coyle says:

      Saw something similar at Fay Bainbridge State Park. Abdomen a little thicker and near small holes/ burrows in sand. Look more like Great Golden Sand Digger.

    • Toni says:

      I had several holes appear in my gravel/sand area in front of my back patio, I thought it was garden snake but today I saw this pretty big orange wasp go into one of the holes its about an inch in size mybe a little bigger I read all the other comments on this web page seems like the same wasp, I live in granite falls wa.

  4. QuiteBuggyHere says:

    Hi all. We have these in NE WA state as well. I live near Kettle Falls, about 45 miles south of the border. They are quite large! They seem to love my spearmint and I only see them around that. Not as aggressive as the yellow jackets, but they are a little aggressive. What about their sting power? As bad as yellow jackets? Worse?

  5. Curious Girl says:


    This looks a lot like the bug I saw last year in Germany (about this time of year also), which was posted here on the site as well. Apparently mine was male since there is no ovipositor.

    Ironically, I’m currently in England now too (and been to Yorkshire). :~)

    This is more likely a headless Ichneumon wasp. Check the wing venation, that stigma should be a tipoff.

    hi my brother and I live in silver furs near mill creek. something bit his leg multiple times and he couldnt figure out what it was. in the truck just now it did it again and he pulled one of these out of his pants. painfull swelling. are these new to the area? can send a pic of it

  9. Becca says:

    I have these as well. Flying low to the ground. They seem to be concentrated near some of my box wood bushes along the fence. I should also mention that I live in Mill Creek as well. Don’t seem to mind me, or my 2 dogs. But I am interested in getting rid of them. Has anyone tried a wasp spray? Or should I call an exterminator to come spray their area? They are completely un-interested in wasp or yellow jacket traps…

  10. Jacquline says:

    My 2 year old son just tried to pick up one of the red ones from our dining room window, he’s always picking up crane flies, only it stung him and he screamed bloody murder for about 5 min. it immediately turned into what looked like a white blister with a dot in the middle then after several minutes later turned red. we live in port Angeles, Washington.

      Thanks for letting us know that there are some species of Ichneumon that are capable of stinging. Most are harmless.

    The photos Stephen posted in 2008 are great. We have the same wasps in our front yard in Lacey, WA. I’d never seen them before and was happy to find out what they are via whatsthatbug.com. Thank you. I don’t know how to post a pic on here or I would share my wasps with you.

    i have these all over in my yard in seatac, wa. just sprayed one in my windowsill if you want it i can mail it. doesn’t look to have a stinger and don’t seem to mind us. they have been around for a couple years and i would like to control them a bit.

    • Stephanie says:

      Jamie, I live in Renton, WA and I’ve been seeing these guys parade my front and back yard since last summer. I would like to control them too, but I have no idea where the nest is. I thought it could have been underground, so I had Scott’s Lawn service come and spray the grass with insecticides, yet it did not affect them at all. I do notice they parade a plant bush that I have, so maybe they are feeding off of that. I caught one and took a picture of it, so I will submit it. Did you find any way to get rid of them yet?

  22. I’ve never seen a bug with these pretty wings

  23. Lindsey Bongiorno says:

    I just had two of these some how get up my pajama pants leg. I was picking things up in the backyard here in Mobile, AL prepare if for tomorrow tropical weather when I felt something like a Nurae who is not that great at putting IV’s in, jab into my shin. It hurt badly! I wasn’t sure if maybe it was and enourmas horse fly or fire ant or what! I slapped my shin real good thinking that should get it! Then it jabbed again!! I LITERALLY stripped out of my pajama pants right there in my back yard(the neighbors can easily see over our privacy fence) . I didn’t see anything at first so I began shaking my pants and 2 if these little buggers fell out of my pants. At first I thought it was a spider because all I saw was legs then I notice wings and though, “is that a may fly or a crane fly? Surely neither of those would have bit me.” So I got a little closer, now let me add that in the midst of I taken off my pants I also used my pants to smush the two bugs just hard enough so that I broke their little wings and just light enough so that theur bodies stayed intact enough for me to study them and figure out what had just jabbed my shin! . Where was I, oh yeah, so I got a little closer and notice that the bugs head was seperate from its thorax like a wasp. I came across the giant stump stabbed wasp, and some others but the color scheme of the bug didn’t match. Then I found this site, and this unidentified Ichneumon! This is what I had TWO of up my pants! Exactly like this! Let me just say that I am a chronically ill patient who has endure a LOT OF PAIN, and I considered my pain tolerance to be quite high, but these two little boogies HURT! Does anyone know if I should be concerned about this bite or sting or whatever??

    • Kerrie says:

      Hi Lindsey – I know exactly what you mean! Did you have any issues after the sting? I got stun in the butt and the red mark and swelling almost covered my entire butt cheek! Days after the redness and swelling is gone but I swear there is a “tickling” feeling – mainly at night in this area. I am hoping it is just the healing . Any knowledge of humans being a host ?

  24. really very beautiful bug . lovely wings.

  25. Tiffany says:

    Do these by chance grow into this color scheme? do they start off black? I have had these show up in my front yard for the past two years but they only stick around for a few weeks then leave for the rest of the year. I have had them return in the spring but I have black little ones first which leave after a week then these show up about a month later for a couple weeks. Just trying to figure out what they are and if I need to worry about them since I need to walk through them to get to my car every morning. Thanks.

    i am totally agree with the author .

  27. Anne Demeter says:

    I am very disheartened by a lot of the posters stating that they were not bothered by these, but then they sprayed insecticide all over the place. Please remember that when you spray insecticide, you are not just killing that one bug that might be bothering you, you are killing almost all species of bugs, many of which are pollinators of our food and flowering plants or feed on other, bad bugs. If it isn’t bothering you, please, just walk away and let it do what it does. Especially since it seems like this species doesn’t sting. Thank you!

    Do they sting

  29. NANCY Burton LUDWICK says:

    I’m not educated in this at all. I can only tell you what I have done wrong and what I’ve done right. Swallowtails will survive if you take them when they are still very small, in your house perhaps in a large glass vase. Supplying twigs, cleaned organic parsley and a plain paper towel at the bottom. My mistake was leaving them outside in a parsley pot and the Ichneumon wasp
    injected a single egg in the caterpillar. I had five. One escaped the wasp but the others all had been eaten by the wasp who were in their chrysalis stage.

  31. Ray Pierce says:

    Just saw one,(just one) in NE Tacoma. Best description I could give is a large paper wasp(yellow and black) lazy flying, and had a long tail. So long I first thought it was a paper wasp carrying a blade of dried yellow-ish grass… 4-7 inches long. Freaked me out. 20years living here and never saw one before.

  32. I love your blog! I am hoping to see more articles from you in the foreseeable future. Really great!!!

  33. Kimi says:

    These Ichneumon wasps are nothing but beneficial to people. The Ichneumon wasp is the kind of good bug you want to keep in your garden, as their main focus is to lay eggs in all those bad grubs, tomato worms, and other caterpillars harmful to your plants.The eggs grow as parasites in the grubs, killing them.Very few species are able to inflict a wound in human skin and they do so only when mishandled. That giant “stinger” is actually the female’s ovipositor (egg laying tube). It carries no venom. It is used to drill a small hole in the host in order to lay an egg. When threatened, a female might try to jab your skin with it in self defense, but it has no poison and would not be more painful than a sliver. They do not live in nests or hives, they are solitary.
