About this speciesRecorded altitude range
20m to 334m
The species is known from scattered localities in the south of England and central Scotland. It is widespread in western and central Europe, but has not been recorded from Ireland.
Habitat and ecology
P. margaritatus occurs on trunks of trees, both pines and broad-leaved, especially when these are covered with lichens. It has also been found on electricity pylons near pine trees and sometimes in gardens on apple trees, etc. It is variable in colour, and camouflaged to resemble lichen on which it sits. Adults are found in May and June.
UK Biodiversity Action Plan priority species. The spider is very local, and although it has excellent camouflage its microhabitat would be searched by arachnologists. It appears to have undergone long-term decline.

Management and conservation
Ensure that old lichen covered trees are given adequate protection, and at sites where they occur a succession of younger trees is provided to replace them when they eventually die.
