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!

I collected and dissected this male Pterostichus (Abacidus). Is there any way that the species can be identified by the genitalia?

Anyone want to describe a new moth species with me lol?
I just discovered that a super common holartic species are two different species between North America and Europe, but I don't have any experience with Lepidoptera taxonomy

Long shot here but does anyone recognize this small harvestman? I collected it from under a rock in central Ohio

This is a weird one. I found a leafmine on Amur honeysuckle. Didn't know they even had herbivore damage!

My partner recently gifted me a piece of Baltic amber! It has this little beetle in it. #Coleoptera do you recognize it maybe?

Does anyone recognize this beetle? It has me stumped.

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

A common type of ant in Europe breaks a fundamental rule in biology: its queens can produce male offspring that are a whole different species

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

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

#Hymenoptera 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?

Hey #entomology folks, anyone know what these nymphs are? They were chilling on a giant ragweed leaf in Ohio.

Old mystery of mine. I found these fossilized (?) bone fragments in a river in the Kenyan Rift Valley in 2018. Does anyone know what they could be from? The porousness of the bone is striking

@ceiseman.bsky.social I found a leafmine on Quercus virginiana that I didn't recognize! Unfortunately seem to have just missed their emergence. The exit hole seems to be covered in some sort of waxy membrane, which is bizarre

Hey #Diptera 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
