Giant Ichneumon

Dear Lisa,
This is a Giant Ichneumon in the genus
Megarhyssa, probably Megarhyssa macrurus.  Because of the long ovipositor which the female uses to lay eggs beneath the bark of deciduous trees infested with wood boring larvae, they are sometimes called Stump Stabbers.  You can read more about this parasitoid wasp on BugGuide.

Your letter to the bugman:  So I found this critter in a shed in Wisconsin.  It’s about an inch long (maybe more).  It doesn’t look like anything I’ve seen, and it was able to hop, almost like a cricket.

Dear Emma,
This is a Hornworm in the family Sphingidae, but we are uncertain of the species.  We will attempt additional research but we are posting your image in the hopes that one of our readers (Bostjan are you reading?) can provide a species identity.  We suspect this individual is pre-pupal and that it was searching for an appropriate location for pupation.

Dead Male Dobsonfly

Dear G8R8RALL,
Your image of a male Dobsonfly corpse is quite impressive, but living male Dobsonflies are even more impressive.  Despite their fierce appearance, they are perfectly harmless, though the female Dobsonfly can bite (no venom) with her considerably smaller mandibles.  The larvae of Dobsonflies are known as Hellgrammites, and they might also bite.  They are considered prize bait by fishermen.

Thank you so much are They prevalent in Maryland literally this is the first one I’ve ever seen definitely never seen a live one how do they where do they hang out and how can you find them and thank you very much again

Hello again G8R8RALL,
Our original response contained links to additional postings on our site that should answer your questions.

Yellow-Striped Armyworm

Dear Joe,
This looks like a Yellow-Striped Armyworm,
Spodoptera ornithogalli, which is pictured on BugGuide.  The Yellow-Striped Armyworm is not listed on the Pacific Northwest Insect Management Handbook of rhubarb pests, but two other members of the genus are listed.  Armyworms and Cutworms are often general feeders and it is sometimes difficult to get a comprehensive listing of all the plants they will feed upon.
