They breed very rapidly and are a cleanerdiet than the usual live pond food. The use of mosquito larvae is almostuniversal among goldfish breeders and is to be in every way recommended.Net-Winged Midges belong to the families of Blepharoceridae andChironomidae, of which the tiny larvae appears more like crustaceans thaninsects. Some of the species, Blepharocera capitata, Chironomus minutusand C. pIomosusy live in the water during the larval and pupal stages, are ofblack color and consist of segments bearing leg-like appendages, eachhaving sucker breathing gills. They usually occur in clusters whichform black patches on submerged rocks.

Some of the flies frequent water courses, ponds andpools in which they deposit eggs and where they pass the larval andpupal stages. Among these are the Moth-like flies of the family Psycho-did<e\ the Crane-flies of the families Tipulida\ Syrphida and Muscida; theFalse Crane-flies, Rhyphid<e; the Black-flies, Empidid<e\ and the Buffalo-flies,Simulidte; Fig. 213; the Horse-flies, Tabanid<e\ the Soldier-flies, Stratio-myiid<£\ the Snipe-flies, Leptid<£\ the Long-legged Flies, Dolichopodid<z;and many others, far too many and too complex in classification for furtherdescription in a volume of this character.
