Nonbug (Order Cladocera?) - Simocephalus
Lewes, Sussex County, Delaware, USA
May 20, 2009
Size: 1 mm
Before I frass these images of a non-bug, I thought I'd share them with our members, if anyone's interested. I believe this is of the Order Cladocera. I would note that this animal has a bivalved carapace.

Please see discussion here. I'll wait a while to give more people an opportunity to contribute to the debate regarding marine taxa, but there is a clear consensus to open BugGuide up to all inland arthropods. I look forward to seeing more of your great pictures of formerly shunned crustaceans, Dave!

Moved from Frass. Tom agreed to trade places.

I am not the seller, but thought of you, when I saw this...

Don't know anything about the book, or if it is a good deal. It came up while I was searching for something else.

Thanks, John. Just today I ordered a couple of textbooks on freshwater invertebrates. Each covers all the orders. I want to begin photographing small freshwater aquatics (those measuring, say, 2 mm or less). Regrettably, many such animals are not "bugs" and so are not appropriate for BugGuide. On the bright side, some small animals that size are -- this morning, I captured an insect larva measuring 2-3 mm. I hope to get some half-decent shots of him for the Guide. Thanks again. -- Dave

Moved from ID Request. Can be viewed here for 30 days

Not an expert
but they look like Copepoda to me. Nice shots!

Thank you
Thanks. (I appreciate all help I can get in ID'ing this [non-bug] critter.) -- Dave
