I found this bug in the shower stalls at my camp and it didn’t bother me, but I have not been able to identify it and would really like to know what it is. I found it in the summer in the New Jersey Pine Barrens.

Ichneumon

Dear Cate,
We believe we have correctly identified your parasitoid Ichneumon as
Xorides stigmapterus thanks to this BugGuide image.  According to BugGuide of the genus:  “hosts: wood-boring beetles, especially Buprestidae and Cerambycidae.”

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.”

Hi – a friend of mine asked me what this is. He said it was ‘bigger than a normal wasp’. Thank you !!!

Stump Stabber

Dear Sue,
This is indeed a Giant Ichneumon, probably
Megarhyssa macrurus, and Giant Ichneumons are frequently called Stump Stabbers because the female uses her very long ovipositor to lay eggs in dead and dying wood that is infested with wood boring larvae of the Pigeon Horntail, a species upon which the Stump Stabbers prey.

Thank you so much !
Sue

Hey, Bugman, our Boy Scout Troop was at Frontierland camp in Clearwater, KS today and we saw this bug and no one knew what it was. We’re hoping you can tell us. Thank you so much!!

Stump Stabber

Dear Karen,
Members of the Giant Ichneumon genus
Megarhyssa are frequently called Stump Stabbers because the female uses her incredibly long ovipositor to lay her eggs in the wood boring larvae of Pigeon Horntails.  Your individual is Megarhyssa macrurus, but we believe the scouts are more likely to remember that they saw a Stump Stabber.

I let my dogs in around 9:45 pm and in came two of these bugs. One stung me, I actually screamed because it hurt. An hour later it still hurts. I need to know what this bug is or my 10 yr old will never go outside again. I live near a pond and I am in Valley Center, Kansas this is located in the central part of the state. 4-16-2017

Short-Tailed Ichneumon

Dear C. Waller,
This is a Short-Tailed Ichneumon in the subfamily Ophioninae, a parasitoid wasp that we believe is to blame for many reports we receive of stinging Crane Flies.  Short-Tailed Ichneumons are attracted to lights, and that might be the reason they entered your home at 9:45 PM.  Though painful, the sting is not considered dangerous.  You might have to rethink restricting the activities of your ten-year old since BugGuide data has the range of Ophioninae as most of North America, with only four states providing no reports:  Montana, Wyoming and the Dakotas.  That does not mean they do not exist there, merely that there have been no BugGuide sightings.

Ichneumon

Dear Josh,
If this is the culprit, you were stung and not bitten.  This looks like a Short-Tailed Ichneumon, possibly in the genus
Ophion.  Most Ichneumons are harmless, but members of the genus Ophion are capable of stinging.  According to BugGuide:  “Adult Ophion species will hunt for their host caterpillar. Usually one egg is laid per host. Caterpillar usually dies during pupal stage though wasp larva remains to pupate itself.”
