Species map 25. Dusky cockroach. Sussex Orthoptera - Online Atlas
For ease of comparison with Haes and Harding (1997), records are shown as: pre-1970, 1970-1999 and as 2000 (onwards). The eventual aim is to update all maps as completely as possible with records for 2001 onwards, to show the status of Sussex orthopteroids in the first decade of the new millennium. Records shown for boundary squares may pertain to neighbouring counties.

1970-1999
2000 (onwards)
Widely distributed in West Sussex; locally common in East Sussex. Can be elusive, even in known localities. Perhaps most easily found on the West Sussex greensand commons (Iping; Ambersham; Coates; Wiggonholt) by searching leaf litter or under heather. There are also colonies in chalk scrub on the South Downs (Arundel Park; Devil's Dyke). In the Ashdown Forest area, there is a colony at Hindleap. Specimens sometimes turn up in unexpected places, such as an adult male E. lapponicus in the High Street, Upper Beeding in June 2000. Males are easily identified. It may be very difficult to distinguish adult females from E. pallidus.
