Clubiona corticalis

One of several very similar Clubiona species – detailed examination is needed for a safe species identification.

This species is most commonly found beneath the loose bark of dead and dying trees though it may be found in a range of other habitats. Habitats include broad-leaved and mixed woodlands, heathland scrub, marsh vegetation, acid and calcareous grassland scrub as well as under stones and in leaf litter, and occasionally in and around houses. Because of its association with trees C. corticalis may be found in birds' nests and squirrel drays.

Adults of both sexes have been recorded in most months of the year, but males are found mainly in spring and early summer, females in summer.

The species is widespread in England as far north as Yorkshire, but scattered in the south-west and Wales.

Status in Leicestershire and Rutland not known.
