Abstract

The literature of the aquatic insect order Trichoptera (caddisflies) is extensive. Ross (1944), Denning (1950a, 1950b, 1954, 1956), Banks (1944) and Betten (1934), among others, have been major contributors to the taxonomy and zoogeography of North American species. Important studies of the general ecology of both adult and larval forms have been made by Lloyd (1921), Scott (1958), and Hynes (1961) but Mecom and Cummins (1964) have commented on the limited knowledge of the trophic relationships of Trichoptera. Hanna (1957), Jones (1950), Chapman and Demory (1963) studied the food ingested by Trichoptera larvae, but except for the very limited experiments of Smirnov (1962), there have been no efforts to determine diurnal feeding activity cycles of caddisflies. It is the purpose of the present study to determine what cyclic or diurnal feeding behavior is present in five selected species and to correlate such activitv with altitude and temperature.
