Species text

T. familiare is found mainly in the south of England. It is widespread in north-western Europe as far north as Sweden.

Habitat and ecology
T. familiare has usually been recorded from inside houses and out-buildings, but occasionally out of doors on gorse and other bushes, and on churchyard walls. Adults have been found between April and July with a peak in July.

This species is uncommon and very local, with most records from southern England and a few from the North.

As far as is known, there are no current threats to this species. However, excessive cleaning and central heating might effect individual populations in some houses.

Management and conservation
Reduce disturbance to a minimum in houses where the species is known to occur.
