I took this picture yesterday at a picnic in Nazareth, PA. Was about 2” long and had a 1/4” to 1/2” stinger. Any idea what the heck it is?

Pigeon Horntail
Hi Todd,
The body coloration on this Pigeon Horntail, Tremex columba, is lighter than the typical coloration, but it is represented on at least one image posted to BugGuide. These Wood Wasps lay their eggs in diseased, decaying or cut wood and the larvae spend several years burrowing and feeding on the wood pulp.

I found this bug in my living room in Southeast Wisconsin. It looks like a winged ant but has a super skinny thorax and seems indestructable. I actually burned it before taking this photo and it still was partly alive.

Unknown Wasp
Hi Josh,
We do not recognize your wasp, but we hope one of our readers will be able to assist in its identification. We wonder perhaps if it might be the little seen male of a species that exhibits sexual dimorphism, like possibly the American Pelecinid, which is only represented by females on BugGuide. At any rate, burning this unknown wasp constitutes unnecessary carnage in our book. Many times people kill benign or beneficial insects because they look fearsome or for other unfathomable reasons.
Eric Eaton provides an identification
Hi, Daniel:
No, that is an ichneumon wasp, possibly in the subfamily Pimplinae:

Not all Pimplinae have long ovipositors. This specimen appears to have a short one, or else it is broken.

My cat spoted this very large hornet thing in our tree. I am farm girl and have never seen anything like this. It was about 3 inches long and the width of my thumb.. Very scary looking. The picture does no justice for its actual size. Please help me!

Cicada Killer
Hi Nikole,
This is a Cicada Killer, a solitary wasp that preys upon Cicadas to feed its brood. Despite its large size, the Cicada Killer is not an aggressive species and we have not received a verified report of anyone being stung by a Cicada Killer, though it is entirely possible that a female Cicada Killer could sting a person. In previous years, the months of July and August have included numerous requests for Cicada Killer identification, but there were very few submissions this year.
What kind of bug is this?

These bugs just showed up and crawl all over the dead tree on the side of my house the long antenna looking thing seems to maybe suck something out of the tree! I have never seen these before and they look like they could be 2inches long some shorter some longer! Its the end of August so we are slowly going into fall.
Thanks, Dawn Bergeron
Giant Ichnuemon ovipositing
Hi Dawn,
This insect is actually depositing eggs into the tree, not sucking something out as you thought. Several days ago we decided to make the Giant Ichneumon our Bug of the Month for September 2010 so we included information on how the female oviposits her eggs in the wood of dead and dying trees that contain the burrowing larvae of the Pigeon Horntail. The Giant Ichneumon is a parasitoid whose larvae feed solely on the larvae of the Pigeon Horntail. Coincidentally, yesterday we posted an image of a female Pigeon Horntail, another impressive non-stinging member of the order that includes wasps, in the act of oviposition. Though we wrote a lengthy response, we were not able to include images of the actual egg laying or oviposition process. Your photos clearly illustrate the process of a female Giant Ichneumon laying eggs, though your species is different from the species in the Bug of the Month posting, which is Megarhyssa atrata. We suspect your Giant Ichneumon is Megarhyssa macrurus. We are going to combine your letter and images with the previously selected letter to be a joint Bug of the Month posting for September 2010.

Pigeon Horntail
Dear Clauson’s,
This is a Pigeon Horntail, Tremex columba, one of the non-stinging Wood Wasps whose larvae bore in wood. The female Pigeon Horntail in your photo is in the act of ovipositing. She uses her stingerlike ovipositor to deposit her eggs in diseased wood where the larvae live and feed. We have gotten some nice recent photos of Giant Ichneumons, which are the primary predator of the Pigeon Horntail.
Giant Ichneumon land on sternum

My wife ad I were heading up to our front door when this thing swooped down onto me. It landed on my chest and after a few awkward pictures, it walked up my neck and flew of my ear. It was very long, I would have guessed 5-6 inches, including the ovipositor. Do you think this a Megarhyssa greenei?
Thanks,

Giant Ichneumon
Hi James,
We have never read a good way to distinguish the members of the genus Megarhyssa from one another, other than that Megarhyssa atrata looks significantly different from the other three relatives. This might be Megarhyssa greenei, though in our opinion, it seems to most closely resemble Megarhyssa macrurus, which you may view on BugGuide.

Very large wasp with orange band

Dear Bugman,
I was in the Goldenrod today and was passed by an enormous wasp. It looked a lot like the Blue Mud Wasp but it had a bright orange band around it near it’s end. It was probably over 3 inches long, but I could not get very close to it before it flew away. What is this thing? Can they sting?
Thanks,
James R
Thread Waisted Wasp
Hi again James,
You really are amassing up quite a collection of images of your local insects on our site. This Thread Waisted Wasp, Ammophila nigrans, is feeding on goldenrod, as are several of the insects you submitted last week. We really are interested in certain habitats, like the Milkweed Meadow tag we just created, and the Goldenrod Field is another excellent place to observe a variety of invertebrates that are either attracted to the nectar or the creatures feeding on the nectar. According to a comment Eric Eaton posted to BugGuide on Ammophila nigrans: “As adults, they feed on nectar. The larva feeds on caterpillars, paralyzed and stocked in the cell by its mother. These are solitary wasps, so each female excavates her own burrow.” The genus information page on BugGuide has more comprehensive information.
Hello Daniel,
Hopefully you don’t mind the numerous submissions, but I work where I can go out to the goldenrod field
every hour or so, so I always bring camera(s) with me. My next home has large milkweed fields, so maybe
next year I’ll have some different varieties. Thanks for the identification; I never had seen one before.
It’s neat that the name roughly translates as a sand-loving wasp… (from B.G. info)
One thing I noticed is that B.G. lists them from 11-25mm (0.4”-0.98”) but I am certain this one was closer to 2.75”-3” long.
Thanks again,
James
Beautiful egg or chrysalis
Location: Cherokee County, NC
August 23, 2010 5:28 pm
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.
