Athetis hospes, or Porter's rustic, is a moth of the family Noctuidae which was described by Christian Friedrich Freyer in 1835. It is found in Spain, southern France, Italy, on the Balkan Peninsula, Crete, Turkey and northern Iran. The species seems to be expanding its range in north-western Europe with records from Great Britain and the Netherlands.
