A very local species in the British Isles, restricted to coastal saltmarsh areas where larvae mass together as they move across the saltmarsh leaving a silken trail.
Known from the saltmarshes of Suffolk.
A single Norfolk record of a female was trapped in a Norwich garden in 2013. The circumstances of this unexplained capture remain a mystery. It is not thought this is from a hidden Norfolk colony, but possibly either bred, hitched a ride from Suffolk, carried on wind or caught in a thermal during the extreme hot weather.
