Hi Hannah,
This is an Ichneumon, a member of a large and diverse family of parasitic wasps.  Most Ichneumons are harmless, but some are capable of stinging, and this does appear to be on of those Ichneumons that sting.

Afternoon,
Found the attached against my curtains this evening
I literally have no idea what it is or what it could be and have been searching images for the last hour trying to find out
Wondering if you could let me know what it is and if it is native to the uk? i have never seen anything like this and i have lived here all my life (some 27 years)

Ichneumon

Ichneumon

This is some species of Ichneumon, a member of a family of parasitic wasps.  Ichneumons prey upon many agricultural pests and most Ichneumons are very host specific, preying upon a single species or genus, though some prey upon entire families of insects and arthropods.  Ichnuemons are a highly diverse family with many members, and we cannot say for certain if you have a native species.  Ichneumons are sometimes introduced to prey upon other introduced pests.

We found several of these in a pile of firewood in our backyard. They have bored many holes in the logs.

Stump Stabber

Hi Michele,
This Giant Ichneumon in the genus
Megarhyssa is commonly called a Stump Stabber.  The female lays her eggs in wood that is infested with the wood boring larvae of Wood Wasps and the larval Stump Stabber parazitizes the larvae of the Wood Wasps.

Hello, I found this bug. It has at least one week living at the same leaf. Here is the raining season. It does not move even when is raining. However it’s alive because when I was taking some photographs it moved a bit. Could you help me to identify this bug?

Parasitized Slug Caterpillar

Dear J.A.K.,
This appears to be a Slug Caterpillar in the family Limacodidae, and it has fallen victim to parasitic wasps, most likely in the family Braconidae.  This image from BugGuide depicts a Slug Caterpillar infested with Braconids.

Dear Daniel,
Thank you for your help. It’s a shame I can’t help this small caterpillar, c’est la vie!.
This “bug world” is amazing, I hope I can learn more.
Cheers,
J Ko.

Hi Mike,
This looks like a parasitic wasp known as an Ichneumon to us, and we believe she was stung, not bitten.  We don’t believe there is any cause for concern, but we are not medical professionals nor are we entomologists, so if you have any doubts, we would urge a visit to the doctor.

Ichneumon

Dear Bill,
We believe this is a Parasitic Wasp in the family Ichneumonidae, a large and diverse family.  According to BugGuide:  “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.”  It looks very similar to this image of
Saranaca elegans posted to BugGuide.  According to BugGuide, the larval food is the caterpillar of “Darapsa myron”, the Virginia Creeper Sphinx, and according to the Sphingidae of the Americas, the Virginia Creeper Sphinx is found in Arkansas.  We may be way off base with the species, but we are confident that we have at least gotten the family identification correct.
