Done in by a Cooper's.
Very cool to see the eyespots and the fake antenna on the wings move, with my new friend PN.
Initially I thought it was a cicada killer wasp, but I have never known them to socialize so I think it must be another species of large wasp. Perhaps they're building a nest?
This darner was wet with dew, waiting for the sun to warm it up and dry its wings. It started vibrating its wings to accelerate the process before it flew off.
This was one of the coolest things we saw all day. My best guess is that it was a robber fly with a strikingly long abdomen. The size and length made me initially think it was a female blue dasher dragonfly, but its flight behavior also resembled a cranefly. The abdomen was black with thing yellow bands or stripes. Other naturalists got better pictures from the top.
Little red spider on underside of dew-filled web.
Terrible photos, but blue-winged warblers were reportedly observed by others that day, and the dark eye stripe seems clear enough.
