Short Tailed Ichneumon

Dear kW,
We believe your parasitic Ichneumon Wasp is a Short Tailed Ichneumon in the genus
Ophion, one of the few genera in the family known to sting.  The sting is not considered dangerous.  According to BugGuide:  “Most all Ophion larva are parasites of caterpillars.”

Short Tailed Ichneumon

Dear Diana,
This is an Ichneumon, a member of a family of parasitic wasps.  Most Ichneumons are perfectly harmless, though there is one genus, Ophion, that is reported to sting.  Your individual appears to be a member of the genus Ophion, the Short Tailed Ichneumons, which you can read more about on BugGuide.  We believe this is the insect that is mistaken for a stinging Crane Fly as Crane Flies do not sting.

So sometime this last late fall/early winter was the first time I saw this bug. later it they started appearing whenever we would leave the door or a window open. My moms first reaction was to kill it so it took a while for me to even be able to catch one. when i caught the one in the photo I couldn’t get a clear photo of it. so i released it in the bathroom and took a few pictures of it then opened the window. when i looked back at the bug it was gone. i found it like a few mins later on the sink ether paralyzed or dead don’t really know which cause my mom found it before i could get another thing to hold it in and she killed it -_-

Ichneumon

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.

Dear What?,
This is an Ichneumon, a parasitic wasp in the family Ichneumonidae, which according to BugGuide has:  “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).  Your individual looks very similar to this member of the genus
Ophion from Idaho that is pictured on BugGuide.”

Hi! I’m trying to determine what type of insect this is. At first glance it looks like a giant mosquito, but then I started researching and thought it could be a crane fly, or maybe a lacewing? No idea, but it’s driving me crazy not knowing!

Hi Cath,
Mistaking this Ichneumon for a Crane Fly is understandable.  Ichneumons are parasitic wasp that comprise one of the largest families of creatures on our planet.  Ichneumons are considered to be harmless to humans, though some species are capable of stinging.

Hello!
I found this lovely lady on my back porch today. We have had freezing temperatures lately and though it reached almost 50 degrees, I think she was pretty frigid. She was pretty easy to scoop up in some Tupperware. After some research I discovered she was harmless and about this time she warmed enough to begin trying to use her ovipositor on my Tupperware. Obviously, she never succeeded, but a couple of times she even tried beginning ‘unzipping’ her abdomen to begin laying eggs. Alas, she couldn’t figure out how to bore into plastic though so eventually gave up. I hope she was able to finish the process outside in spite of the dropping temperatures. I have seen many Ichneumon in our area, but never her particular species. I couldn’t get a good shot of the ruler, but from antenna to ovipositor she was about 5 inches.

Dear Heather,
A female Giant Ichneumon or Stump Stabber is an fearsome looking, yet harmless parasitic wasp.  Other than
Megarhyssa atrata, we are reluctant to attempt a species identification on members of the genus.
