Purseweb spider — size comparison — facts and sources
The purseweb spider Atypus affinis inhabits warm sites in Europe and neighbouring areas. It uses heathland, grassy edges and places with soil suitable for making a burrow, among other habitats.
It builds a long silk tube, most of which lies underground, with a surface section among surrounding plants and debris. When an insect walks over this covering, the spider seizes it through the silk, cuts the wall and pulls the prey inside. After a successful hunt it may repair the damaged part of the trap.
Females remain associated with their retreats, and clusters of tubes may reveal several individuals on a small patch of suitable habitat.
