I am sorting through a bunch of Malaise trap samples from Thailand from which all the insects larger than about 2 mm have been removed. The absence of larger insects makes all the tiny ones stand out, so these samples, the “microfraction” are golden. They are full of treasures: usually overlooked tiny things like Chonocephalus, termitoxeniines, and weird Metopina group males. I’ll publish more photos soon, but here are a couple I photographed previously.
Note the shieldlike crest on the back of the head in the second photo. Totally bizarre.
Microfractions represent yet another largely unexplored frontier of tropical phorid diversity. After nearly 30 years of doing this, I can still be amazed and awed by “my” flies.
