The genus Enoicyla is unique among caddisflies because the larvae are terrestrial, living in leaf litter.

Enoicyla pusilla has a widespread but discontinuous distribution in Europe.

In Britain, it is found chiefly in and around Wyre Forest, Worcestershire and adjoining counties.

[2] The females lay eggs shortly after emerging in the autumn and they hatch about two weeks later.

[3] There are five larval instars between December and April and fully developed larval cases are about 8–9 mm long and 1.5–2 mm in diameter.
