This Costa Rican Assassin Bug is sporting its "don't touch me/I'm dangerous" colors. It was temporarily captive, photographed with flash in a lightbox, and released. Canon 1D X, Sigma 150mm macro, f/16, 1/160, ISO 100, hand held.
A very apt name, he /sh certainly looks spooky. Is that yellow appendage an ovipositor?
Well focused and exposed, the use of flash is optimal, no objectionable highlights. My only suggestion would be to increase the image size.
Nice image of a dark subject. Tricky exposure done well. Interesting bug. I have seen Assassin bugs in WI, they seems to be armored, yellowish and brown colored and hairless.
