He/him PhD student in the Carstens Lab at The Ohio State University
pinned post!
I would like to announce that I'm starting my PhD this fall in the Carstens Lab at Ohio State University! I haven't nailed down a specific topic yet, but it will most likely be in computational evolutionary biology using insects as a study system. I'm very excited to take this next step!

Productive day looking for galls! I found a few common ones for my area of Ohio + 2 galls that seem to be entirely new.

This little guy came out of some Cecidomyiidae galls I collected. I think it's a beetle...? No clue about family though.

thoughts about this wasp? It's clearly a Eulophid and I've tentatively keyed it to Entiinae. I reared it from the Cecidomyiid Neolasioptera vernoniae. However, Entiinae is virtually unknown from midge galls sp I am skeptical. Does anyone want to make a better guess?

folks, I have a really weird mystery going on. I reared two Tachinidae flies from empty Rabdotus snail shells that I thought were still alive (they were glued down to vegetation) It doesn't seem to key to any genus, and no recorded Tachinid parasitizes snails
