Overview

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.
