Caenidae (Trico)

Caenidae, the smallest ephemeral that hatch typically in the middle of summer, sometimes causing crazy fish, but more frequently fishermen. Fly-fishers call it the "white curse". The passage from Dun to Spinner and Spent happens in a short time, so during the hatching it can happen to have to deal with all the vital stages of the insect, and it becomes essential to understand which is the preferred one of the fish.
