Other "flies"

In addition to the aquatic insects and terrestrials discussed on the previous pages, there are several other insects and insect groups that deserve a little attention.

“Mighty are the midges -  not in size, perhaps, but certainly in numbers and distribution in trout waters. These two winged mosquito-like flies are perhaps the single most important aquatic insects that trout eat. yet most fly fisherman do not realize this, and thus isolate themselves from what I consider the highest plateau of matching the hatch for trout.”...Dave Whitlock’s Guide to Aquatic Trout Foods, first paragraph of Chapter 7 “Midges and Craneflies”

Midges are of the Order Diptera (Flies) from Greek 'two-winged'.
