Apis marshamella Kirby, 1802, Nomada marshamella var. dubia Schmiedeknecht, 1882, Nomada marshamella var. modesta_homonym Schmiedeknecht, 1882
This cuckoo bee is easily confused in the field with its close relative Nomada fulvicornis Fabricius (see remarks under that species).
Distributed throughout much of Britain, from southern England to northern Scotland. Similarly widespread in Ireland. It is known too from the Inner Hebrides (Rum) and the Isle of Man. Surprisingly, there are no records of the bee from the Channel Islands, despite the abundance on several of the islands of its main host bee, Andrena carantonica Pérez (= scotica Perkins).
Widely distributed in Europe, from southern Finland (Söderman & Leinonen, 2003) to Corsica and Malta, and further east to Turkey.
