Detail of insect being eaten.
Input from others so far on the identity of the insect is:
- a Hemiptera (true bug), most likely of the family Pentatomidae
- a Katydid (Microcentrum rhombifolium). The general color is good and the wings are semi transparent.
- I can't be sure but looking at your picture it looks like a Lace Wing, a very beneficial insect.
- Although the insect is semi-crushed, I am reasonably certain it is a treehopper, f. Membracidae. These bugs have a pretty hard pronotum that might make them tough to eat. The are also called three-cornered hoppers because of the thorn like processes. Looking like a thorn also allows these bugs to hide in plain site. Here's a link to a pretty good picture of the bug in uncrushed form: http://bugguide.net/node/view/230006/bgimage
- The insect is to squished and bleary for a comfortable id. The bird looks great! Possibly a stink bug. Pentatomidae.
- a Hemipteran (something like a leaf hopper) in the suborder Auchenorryncha and the family Cicadellidae - based on the shape of what he thought was the head and the size/shape of the wing. He said it could also be a small green cricket but he couldn't see any antennae.
