My contribution to Michelle's Nature Notes (#389).
I think this is a Pearl Crescent Butterfly - Phyciodes tharos:
Cloudless Sulphur, Phoebis sennae:
I thought this was a beetle. It is an Ailanthus webworm moth:
Female Eastern Pondhawk, Erythemis simplicicollis:
I'm also linking to Carmi's Thematic Photographic 382 - Street Signs. These signs are around (or on) the W. and O.D. trail.
