Unidentified Mexican beetle, under 3 mm.
This time, there were many dead beetles, and as many tiny, almost transparent larvae, very much alive. But only one live adult, so there won't be any mating photos this time. (They were very enthusiastic about that in 2008.)
But at least, now, I've got a decent face shot. I love this Egyptian Pharaoh headdress. The decoration in the centre of the forehead is a patch of tangled golden hairs.
Now to send him off to BugGuide for a name to the face.
