Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

I guess beauty is in the eyes of the beholders! These guys are frequently waxing poetically about the "lovely fish". Maybe they don't have any other species. I'm a bit confused - the poster is from Viet Nam but I'm pretty sure the fish were caught in some lakes in England. The countryside surely looks more like what I'd expect inland England to look like and not the lush vegetation of tropical Viet Nam.
