Wowee, that last one is impressive. That's a Glyphipterigid Sedge Moth (easy for me to say). They all look alike, but there aren't many species in Ohio. If you don't hear from Bugguide, I may work on it.
Dennis- Someone has recommended Diploschizia. I'd say it's a pretty good match. If I'm reading the guide correctly, there are only six species in that genus in the U.S. I have a nice sedge fauna in the backyard. :)http://bugguide.net/node/view/946397
Yes, most Diploschizia species are found in Florida. That may be due to the expert (J. Heppner) having surveyed the state thoroughly. They are more poorly known elsewhere, but I'd put my money on D. impigritella, the Nut-sedge Moth. It has the widest range, including Ohio.
Nice macro shots Tom, I didn't know you had a blog, I'm now a follower.
Solomon, I once posted here quite a bit, mostly in my formative years, pre-kid. I'm trying to post more, but take a look at all the 1000+ posts I've compiled- there's a nice list of keywords in the right hand column.
Tom, your insect macro photography is stunning!
Thank you Lisa- I've got great equipment that I've seriously underused lately. I'm trying to remedy that.
It is amazing that these are all in your backyard, going unnoticed until this!!
