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

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!

Speaking of aquatic critters, do you recognize this tiny Ostracod? I found it in an Ohio River

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

@kmagnacca.bsky.social is this Gonatocerus?

Does anyone recognize this beetle? It has me stumped.
~1 mm long, collected from turfgrass on the OSU campus

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

Whatever it is its changing shape and color... is it pupating or just dying??

Theres also this new freak that just appeared. I think this is one is a Mordellid though?

It seems to be spinning a silk structure inside the rearing bag. Doesn't seem very beetleish to me?

Not in this area anymore, but this tiny gall wasp gall on Southern Live Oak is everywhere on almost every tree, but I was apparently the first person to find and document it.
To be fair, the galls are like 1 mm long

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

Look for galls on them!! I've been recently collecting a bunch since they're so abundant here in Ohio

#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

Here is the subscutellum confirmed that is is in fact Tachinidae

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

I figured out they are Sarcophagids! Only they have a pit like this on the tail end of the pupa with the spiracle pair inside, apparently

The culprits. I'm gonna try and rear them to see what they are
