Horn-tail Wasp Dies While Ovipositing - Tremex columba - Female
Indian Creek Nature Center, Cedar Rapids, Linn County, Iowa, USA

I found this wasp attached to a maple tree trunk, and when approched, I noticed it didn't budge, after poking it a few times with a twig, I realized it had died apparently while ovipositing. Could it be a fungus? I noticed there were some white powder like granules on it's head and thorax region. This is what I possibly thought was fungus, or the beginning of fungal fruit, Cordyseps possibly?

Moved from ID Request.

These wasps, after laying all their eggs, often die while still embedded in the tree. See

Interesting, thanks for the c
Interesting, thanks for the comment. I guess it never accured to me it could've just been natural.
