Essex Red Data List comment
Old record for Epping Forest

Species text
This crab spider appears to be scarce, with scattered records in the south of Britain. At most sites only a few specimens have been found, but the spider may be slightly under-recorded because it matures early in the season. The spider occurs in a fairly wide range of grassland habitats, and has also occasionally been found on heathland and coastal under-cliff in Dorset. Both sexes are adult in April and May. In Essex it was found in 2005 in large numbers at a site in Basildon. The only previous county record had been from Epping Forest during the 19th century, found amongst specimens labelled as X. luctuosus in the collections of O.P.-Cambridge and A.R. Jackson (Locket, Millidge & Merrett, 1974). References
