Spider beetles are not predators like their namesakes but are instead pests of stored grain.  I was surprised at how difficult they were to photograph.  Their round bodies were hard to fit into a single focal plane, while their reflective elytra were prone to harsh glare.  I could not do much about the first problem, but the lighting was solved by placing the beetle inside a white box and firing an off-camera strobe into the box but away from the beetle.

  2. I’m intrigued by the fine, dense, rust-colored pilosity covering the appendages – I didn’t realize they had this (maybe just this species). Of course, I’ve never seen such a detailed macrophotograph of one either – nice shot.
