Species Profile
Cryphoeca silvicola is a small species of dwarf sheet spider in the family Cybaeidae which has a Palearctic distribution. The generic name, Cryphoeca, means hidden and the specific name silvicola means "living in the woods".
The kleine bostrechterspin (Cryphoeca silvicola) is declining primarily due to habitat loss and fragmentation of old-growth forests. Intensive forestry practices and urbanization have reduced the availability of suitable microhabitats, particularly the specific bark crevices and deadwood structures this species requires for survival.

Habitat & Distribution
The species is found in the litter layer of coniferous forests, from lowland regions up to low mountain ranges. In Britain adult Cryphoeca sylvicola have been recorded as being active in all months of the year with peaks in the spring and early summer and in the autumn.
