Nomada ferruginata

Range & Status

This Endangered (RDB1) and Biodiversity Action Plan (BAP) species was recently (2007) added to the Cornish aculeate fauna from Merthen Wood on the Helford Estuary. A rare species, but formerly widely distributed in southern Britain. There were no records between 1949 and 1987, however, in recent years the species has undergone a resurgence with records form various south-eastern counties. The Cornish record represents a rather disjunct population, the nearest other record being from Dorset. This species is a cleptoparasite of the mining bee Andrena praecox which has also recently (2007) been recorded as new to the Cornish aculeate fauna from Draynes Wood on the edge of Bodmin Moor.
