Habitat and Ecology
The species is a brood parasite of other bees, Andrena bicolor is a host (Schindler 2004), also Andrena chrysoceles (Schindler 2008). Probably also Andrena angustior (Perkins 1919, Tscharntke 1984) and Andrena allosa (M. Schwarz pers. comm. 2013).
Nomada fabriciana is bivoltine (it has two generations per year). The spring brood flies from early March to the beginning of June, the summer one from June to mid August (the two broods may overlap). The second brood is considerably less plentiful than the first. In Ireland, Stelfox (1927) detected no evidence of a second brood.
The main host (Andrena bicolor) lives in all kind of habitats: edges of forests, abandoned vineyards, verges, parks and gardens.
Possibly the male scent marks by putting pheromones on the edges of leaves of bushes (Smit 2005).
