    More than any other group of macro-organisms, true flies (Diptera) dominate the freshwater environment. Nearly one-third of all flies—roug species—have some developmental connection with an aquatic environment. Their abundance, ubiquity, and diversity of adaptations to the aquatic environment position them as major drivers of ecosystem processes and as Cited by: 4.   Trout fishermen tie flies to imitate them, and taxonomists study them. Included here are books on fly-tying and fly-fishing, and insect orders that are primarily aquatic: Trichoptera, Ephemeroptera, Plecoptera, and Odonata. Most books on aquatic Diptera (mosquitoes, midges, horseflies, etc.) will be found in our Diptera catalog. View the Full.

Diptera (true flies) is a large and diverse order of insects, in terms of number is second only to beetles (Coleoptera). Like in other large orders, most species are terrestrial. However, among aquatic members, Diptera is the most diverse of all insect orders.

The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and (at most) one pair of functional, membraneous wings, which are attached to a complex mesothorax.

The second pair of wings, on the metathorax, are reduced to order's fundamental peculiarity is its remarkable. The order Diptera, or true flies, is a major aquatic insect order representing 43% of known freshwater insect species (Balian et al., ).

The most species-rich families are Chironomidae, Culicidae, Simuliidae, and Tipulidae, but other smaller families constitute an important portion of the freshwater Diptera diversity (Balian et al., ).

Scuds are not insects but small crustaceans, sometimes called freshwater shrimp, and in some streams they are a primary food source for trout.

They grow quickly and can survive in a variety of habitats, but they are most prolific and important to trout in slow, weedy spring creeks. Unlike most aquatic insects, they never "hatch" into a dry form. BOOK REVIEWS Aquatic Diptera.
