Distribution and habitat
This species is native to Europe. It extends over whole Europe eastwards to Northwestern and Northern Russia.[2][1] The aquatic stages of Philopotamus montanus can be found mainly in small rivers in uplands, in brooks and rivulets and in stony streams, often with rapids, as this species prefers high current velocities.

Description
Larva of Philopotamus montanus
Philopotamus montanus can reach a body length of about 4–9 mm (0.16–0.35 in), with a
wingspan of about 12–20 mm (0.47–0.79 in). These medium sized caddisflies are usually light brown or yellowish colored, with many dark brown spots.
Biology
Philopotamus montanus has one generation a year (
univoltine). Larvae build long, tubular nets attached to rocks. They are filter-feeders, mainly feeding on small, particulate matter, fine particles and diatoms. Adults of these caddisflies are on the wing from February to October. [5]
