Cymatodera sp. Checkered Beetle (Cleridae)
photo details: Canon 100mm f2.8 macro lens on a Canon 20D
f/16, 1/250 sec, ISO 100, indirect strobe in a white box
The bumps/pits on the elytra - do they have a purpose like in the Stenocara sp. of Africa?
Hmm... looking at the photo details - "indirect stobe in a white box" ..you mean the strobe is in the whitebox or the beetle in a whitebox flash outside like traditionaly small product photography? Whatever the method the results are wonderful.
I have no idea about the elytral pits- I'd assume they help reinforce the rigidity of the elytra. Lots of different beetles have them.
I've got a large cardboard box, entirely white inside, that serves as a little bug photo studio. I fire the flash inside the box and I get an even white light, as for product photography. This isn't really a field technique...
