Collyrinae a. - Rhyssa - BugGuide.Net

Thanks

Moved from Ichneumon Wasps.
That makes a lot more sense.

Ichneumonidae...

This is surely NOT a giant ichneumon wasp in the Megarhyssa genus. The Rhyssa genus is possible however.

From these photos, there are some suggestions for the subfamily Collyrinae such as lack of an areolet & weakly compressed abdomen, but nothing here that is definitive. If the owner feels comfortable that all the characteristics have been met (since he has the specimen), than he should surely say so, otherwise, I would place this among the other ichneumons in the guide.

According to The American Entomological Institute there is only one introduced species, Collyria coxator in North America. So it is either this species or it should be moved back.
Furthermore it doesn't look like this image of a female.

Thank you for your looking . . .

From what I can determine Collyrinae is the best fit. From the tip if head to the end of tail it only measures 2.5 cm. Of course, with such a large and diverse group of insects I will never be 100% certain.

Giant Ichneumon

It looks like some kind of Giant ichneumon wasp. I can't exactly pinpoint specie though.

Rhyssa?

Reminds me of a Rhyssa, but I can't be certain, either.
