Habitat and distribution

Trachyzelotes pedestris usually occurs in chalk and limestone grassland, often under stones in fairly open habitat. In Essex it occurs on dry south-facing grasslands, landslip areas and at the base of sea walls. It has occasionally been found in open sandy areas on Breckland heaths. P. Merrett notes an occurrence in his kitchen sink! (limestone grassland nearby). Egg-sacs are deposited under stones. Adults of both sexes have been recorded between May and August, mainly in June.[2]
