This is a giant swallowtail Papilio cresphontes, which landed in deep shade a few feet from me as I walked along Slaughter Creek.
This is a tiny brown butterfly, most likely a fatal metalmark (Calephelis nemesis) or possibly a Rawson's metalmark (Calephelis rawsoni). They can only be told apart in the field if you have a ventral view of the hindwing, and since it was disinclined to fold its wings and I was unable to get below a butterfly on the ground, I am guessing this is the more common of the two species, C. nemesis. I don't know why it's called a fatal metalmark. A brief search on the web shed no light on the matter.
Here is a blue dasher (Pachydiplax longipennis) which has almost worn out its wings. I like blue dashers not only because they are nice looking dragonflies but because it's easy to take pictures of them, and they also assume nice poses occasionally.
This damselfly is a tough one to identify. I think it is a female dusky dancer, Argia translata, but females of Argia species are very hard to ID with certainty.
