Experimented with the new black light and the "Larry's light house" from BioQuip:

It's quite nice, although my pictures still aren't too hot... :( I have my camera on the finest settings, but they still tend to come out blurry. Ah well. I'll keep experimenting...

Will look up this beetle later -- I think I've observed some like it before...
