identify this bug please
This is a wheel bug, Arilus cristatus. it is in the Reduviid family, also called assassin bugs. It is a predator and thus a beneficial insect. You can pick them up but stay away from the mouth parts because they can give a painful bite. By the way, this is an outstanding picture. I would like permission to use it for educational programs. If you would not mind emailing it to me at email@example.com and giving me the name of the photographer so that I can properly credit it I would appreciate it.
