Jim's best bet is to photograph pinned specimens. It would then be easy to get accurate photos of the dorsal and ventral wing surfaces. I know a few collectors in Jim's area but it would probably be best if he contacted the Entomology Dept. at the LA County Museum of Natural History or the Entomol. Dept. at the University of California Riverside. They both have butterfly collections, the LA Museum one being more extensive.

I'm an entomologist and have access to collections. I'd be more than happy to take photos for Jim but based on his experience with fish, this may not be an option for him.

Jim, keep in mind that different butterflies species hold their wings in different positions when resting, have different flight characteristics, and in general different behavior. I don't know how reallistic you want or can get in your screen saver.
