Trichia hispida Trochulus sericeus (Draparnaud, 1801)[3] Trichia sericea (Draparnaud, 1801) Trochulus hispidus, previously known as Trichia hispida, common name, the "hairy snail", is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Hygromiidae, the hairy snails and their allies.

In colour the shell is brown to cream, sometimes with a light band at the periphery.

The periostracum is irregularly striated, and densely covered with short (0.2-0.3 mm), curved hairs.

[8] A hairy snail was found in the plumage of a great tit (Parus major) wintering in southwestern Poland in 2010.

This passerine was the smallest bird species reported to carry a gastropod.
