Hi bugman! I’ve seen several of these bugs since moving into my apartment in suburban Philadelphia in 2007, although I usually find them dead under the TV stand. This guy, and one of his relatives a few days before, were alive. His relative was on my screen door at night (attracted to the light, maybe?) and was a lighter yellow color, while this guy is darker and managed to make it inside to the front window. After I snapped this photo he started flying around torturing my cat, so I whacked him with a flip-flop (I’m sorry! I don’t usually kill) and he had an incredibly hard exoskeleton – all my weight didn’t kill him. If he’s not dangerous, I’m content to try and catch them and put them outside if I ever find any more. Do you know what he is? We’ve had typical spring weather for the last few days – cool at night, warmish and alternating between damp and sunny during the day. Some of them (not this guy, but others) look like th ey have a large stinger.

Possibly Scorpionfly

Nocturnal Ichneumon

Dear Colleen,
We are not certain of the identity of this insect, but our best guess is a Scorpionfly or other member of the order Mecoptera.  It looks somewhat like this member of the family Panorpodidae that is pictured on BugGuide.  We will try to get another opinion.

Daniel:
That is one of the nocturnal ichneumon wasps.  Not enough detail to place to subfamily, let alone genus, species.
Eric

Daniel,
Thank you SO much! A quick Google search of Ichneumon wasps makes me think Eric was right. Good to know that’s an ovipostor and not a stinger. Looks like my kitty cat is safe :) Again, thanks – I didn’t expect such a quick reply!

Hi there. Attached is a picture of a wasp-like creature I found in my windowsill. I’ve never seen one before and a friend who lives nearby also found one in her house and has also never seen it before. We live in Whangarei, New Zealand which is in Northland (at the North of the North Island). We wanted to make sure it wasn’t a new immigrant.

Ichneumon

Ichneumon

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.

Hi there – we ran across this guy in the Shenandoah National Park in the state of Virginia, very near a small mountain stream. We tried to look around on the computer, but couldn’t find a definitive answer and the curiosity is pretty intense now ;). Any folks out there know what this is?
Thanks!

Ichneumon

Ichneumon

Dear Curious Virginian,
The best we can provide for you at this time is a family name.  This is an Ichneumon Wasp in the family Ichneumonidae.  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.”  Even if we were able to locate a similar looking individual by browsing through BugGuide, it would most likely require an expert to definitively determine the correct species.

Subject: Is it, could it be… a “Fairy Fly” wasp?

Olá WTB?,
I was on the laptop the other night, even looking at WTB when I saw a tiny, tiny bug on the screen, grabbed the camera and took some photos. The bug was very accommodating, apparently quite interested in the light from the computer screen. Finally though I encourage a transfer onto a paper receipt so I could hopefully get some better pics not in a backlit. But, still the tiny bug stretched the limits of my little camera.
It would seem the bug is at least a tiny wasp, but… is it possibly a fairy fly wasp? S/he seems to have long enough antennae and be small enough (that’s my middle finger in one of the photos and I have small hands). The receipt shows numbers on the other side that only measured about 1mm so that’s the size of the little flyer too.
Still February in Porto but the bugs are not waiting.
Thanks again for all you do. :)

Parasitic Wasp

Dear Curious Girl,
We are posting your photos, and we hope some eminent expert on Parasitic Hymenopterans can provide you with a conclusive identification, but that is beyond the scope of our ability.  We believe this is some type of Parasitic Wasp, and you can view a wealth of species from North America on BugGuide.   At last, we are getting some rain in Los Angeles, but the experts warn that this is not a sign that the drought has ended as the snow pack is still well below average.  This rain will doubtless result in a fabulous display of desert wildflowers in the coming weeks.

Cool Daniel.
Do you think it could be Aphidiinae Braconidae (Braconid Wasp)?
Apparently they are part of Integrated Pest Management against aphids (and they get really convoluted when they attack). Funny as I did get a picture of an aphid just outside too that day though I wasn’t trying to get that one.
Here’s a couple bonus pics (though the “bug” doesn’t look much different in them). Hope you find them cool.
Plus, even though I know it messes with your system I’m sending a couple of a different tiny wasp from London’s Hyde Park last September because it came up in my search and they are so similar plus I just realized the victim for this wasp might be on the flower too! You think? I don’t believe I knew either were there when I took the picture. I think I was just trying to get the flower and the bonus was bugs.
Very cool on finally getting some rain, and hopefully some great flowers (take pictures!). I was in Death Valley once when it rained and it seemed almost immediately a bajillion tiny, tiny flowers carpeted the desert. As you no doubt know, lack of rain has not been a problem in this part of the world (especially the UK). When I was there in March ’12 they were thinking there might be a drought, so implemented water conservation only to have the 3rd wettest summer ever (which of course I also was able to experience… ::sigh::).

Parasitic Wasp checking out WTB?

Hi again Curious Girl,
We couldn’t resist posting your new photo in a shameless bit of self promotion.  We are also including your London image with the same posting, discarding all efforts at “neat” categorizations.  It has been pouring all night in Los Angeles, and we are expecting the rain to stay with us for over 24 hours.  It is a perfect day to stay home by the fire, but alas, we must soon drive to “the valley” for work.  We are not looking forward to the hectic morning commute.

Hi,
Live in Ghana, west Africa, these bugs keep appearing in my bedroom, never seen them before anywhere else. I’ve lived in the US before and never saw them there either. My biggest concern is if it is harmful, like carry some disease. Please help! Thanks

Ensign Wasp

Ensign Wasp

Dear ND,
This is a Wasp, not a Fly, and it does not carry disease.  We are surmising that once we tell you that this is a beneficial Ensign Wasp that parasitizes the ootheca or egg cases of Cockroaches, helping to reduce their populations, that no additional individuals will fall victim to Unnecessary Carnage.

Dear Daniel,
I really appreciate the information and advice, especially knowing how much you have to work on each day.
I also want to assure you that these wasps will no longer suffer at my hands.
Best Regards
Nukunu

Crane Fly

Ichneumon

Hi Tara,
We believe this is a Crane Fly in the family Tipulidae.  There are some images on the Brisbane Insect site that look similar.

Hi,
on Feb. Feb.20, 2014 “Tara” posted an isect from New South Wales, Australia.  You answered that this might be a crane fly / Tipulidae, but if you look at the wing venation it is evident that this insect does not belong to the Diptera at all, it’s Hymenoptera. It’ another parasitic Hymenoptera, Ichneumonidae or Braconidae. You may compare the wing venation of a Tipulidae here: http://www.metafysica.nl/nature/insect/hennig1954_7.jpg

Thanks Erwin.  Because of an earlier comment, we have already addressed this error, and we will add your comment to the posting.
