Just a comment on what I used for this image -- I bought one of those small, clear plastic boxes sold in variety stores for hobbyists. The containers work well for taking these views since you can turn them over to get the ventral view and the insect can't escape.

I've just been flipping them over, and they do that defensive pulling-in of the legs and head so not all the useful details are visible. Good for color and postcoxal lines, but not mouthparts and tarsi. I have a lot of clear gem vials (I collect gemstones when it's too cold for insects) and they're just the right size for a lady beetle.
