Hello all,

First of all I hope I am in the good forum for this request.

A friend photographied that nest within a Eastern bluebird nest box in Sherbrooke, Quebec, Canada (near Vermont, USA).

It doesn't look as a hemynoptera nest but I think it is something created by diptera larvae. Am I wrong???

Any idea about which kind of insects (family/genus/species) built it???

Thank you,

Michel

Hello Michel,

Welcome to the Forum. To be honest I don't know what your item is. I suspect that it is Hymenopterous in origin, but I cannot gaurantee that. I think your best bet, would be to Email the picture to any of the Canadian Natural History Museums. They will certainly know what it is.

Hello Harry,

Funally the suspect #1 is a little moth who would have parasitized a bumblebees nest!!!

This little moth would have been from genus Aphomia (Pyralidae family) which is specialized on Bumblebee parasiting!

I just learned something myself!!!

Cheers,

Michel
