Thanks, Jeff. I actually HAD rinsed the beetles off that I retrieved from that trap, mostly because they smelled like rotten fish! I love fish, but YUK! I just found out yesterday that a little flash ring can be ordered for my camera, which surprised me. I just use a tiny shirt pocket model, and definitely plan on ordering the ring. For those pictures, though, I just mounted the camera on a miniature (and I do mean tiny) tripod and aimed a "high intensity" light at the cereal bowl (if you call 20W high!). I probably should have taken the setup outside into the sun. I think the ring flash will work better. The third picture in the series (or was it the first?) shows the striations a little better.

Thanks, Jim. I actually have a light ring for another camera, and may try to rig something like that. Certainly I need a little more than a 20 W high intensity goose neck lamp and a white cereal bowl! :)
