One of the more common large Ectemnius species easily identified in both sexes by the densely striate mesoscutum with transverse striae on the front half.
Widely distributed in England and Wales, and frequent in many areas. Rare in Scotland, with the most northerly record to date from a site in the Dundee area. Recorded in Ireland for the first time in 1996 in County Dublin (C Ronayne, pers. comm.). Well established in the Channel Islands. Nomenclatural confusion within the genus up to the beginning of the century renders many old literature records unreliable. A Holarctic species occurring throughout much of Europe from England to the Urals and Caucasus; also in south-east Canada and north-east USA, where it may have been introduced (Lomholdt, 1975-76).
