Spider in a Bottle

I caught this Phidippus (audax?) jumping spider in my yard, in a plastic centrifuge tube (like a tall, thin prescription bottle). I intended to release it in a spot outdoors where I could photograph it... but it settled down deep inside the bottle and started grooming. So I took its picture by aiming down into the tube -- I think the milky-clear plastic added some diffusion to the flash! Nikon D800, 105mm + 36mm extension, 1/60th @f/16, ISO100, diffused flash.
