Palo verde beetle eye
110 image stack of a palo verde beetle's eyes at 5 μm step/frame. The beetle was found in a very dusty spiderweb (due to the massive size of this beetle it was most likely not killed by the web, but just ended up there as it died after laying its eggs) by a friend of mine at work.
I carefully cleaned the 4 inch long beetle with a small paintbrush but some of the dirt is lodged in crevases to small for the (microscopically large) bristles to reach.
Taken with the new 10x LOMO Q-plan objective.
