Abstract
Caddis– (or sedge) flies being in close relation to the butterflies comprise the largest order of aquatic insects. Known number of species on Earth approximately 13,574. Imagos are greyish-brown, fragile terrestrial insects resembling the moths (Fig. 301/1). Their body length ranges from 3 mm (microcaddisflies – Hydroptilidae) to 60 mm (large casemakers– Phryganeidae).The scientific name ‘Trichoptera’ means ‘hairy winged’, which refers to the fact that wings of caddisflies are covered by hairs, not by scales like those of the butterflies. The mouthparts of mature animals are vestigial, but may be capable of ingesting water and nectar.
