Episyron rufipes is a specialist hunter of orb-web spiders. Araneidae (Araneus) and Metidae (Meta) are the usual prey, with a few records for Lycosidae.
Episyron rufipes is widespread in lowland Britain on any sandy soils. Away from the south-east heaths and coastal systems, inland records are scattered north to Humberside. In Wales, north west England and in Ireland, E. rufipes is mostly confined to the coast.
