Interesting entry - certainly harsh! My preference would be to have a sharper depth of field (f/16 for example) in this shot, so more of the infestation is in focus. Good tight crop - it works well to show this harsh environment.
WOW that's amazing, look at all those little guys! Nice macro work, I also like your choice of DOF; it really works well here. Lighting is on the money, one of the best shots in the challenge IMHO.
A clever take on the challenge, with a nod to a classic DPC cliche. On my monitor it appears a tad over bright, but nontheless, one of my higher votes.
