I found this caterpillar nest in a tree in my front yard. I have been watching it, waiting for them to come out to see what happens. I shot a series when I got home from work. It was getting dark so I tried some fill flash to brighten them up a little. Shooting close up with a 300mm lens gives an almost abstract pattern to the closeups. I also shot a few 2 shot vertical panoramas which I assembled in Photoshop.
I saw some of these a few weeks ago too. Your photos are excellent!
