Glyphotaelius pellucidus is a caddis fly from the family Limnephilidae . The adults are relatively easy to recognize by the marbled forewings with the characteristic arched indentation at the tip. With a body length of 11 to 16 mm, the forewing length is 12 to 17 mm and the wingspan is 26 to 36 mm.
Their one-year development cycle begins with the laying of the egg packets surrounded by jelly in the riparian vegetation of waters between the end of August and the end of October. After about 25 days, the mature larvae fall into the water. Larvae that do not fall into the water can move over land to a limited extent and, if they cannot reach the water, go to rest.
In the water, the larva begins to build the quiver from elliptically bitten pieces of fallen leaves. In calm waters, the housing can be up to 60 mm long and 30 mm wide, in flowing waters it is significantly smaller and rounder. The larvae pupate in March / April, the adults hatch in April / May.
Glyphotaelius pellucidus also lives in sometimes dry waters and spends in the imaginal stage a diapause in caves and other cool and humid hiding spots during the summer.
