Cleptoparasitic: Hosts; Andrena tarsata (R.C.L. Perkins, 1919g; G.M. Spooner, pers. comm., and various other European authors cited in Westrich 1989 and Smit, 2018).
In mainland Europe, Peeters, Raemakers & Smit (1999) additionally cite Andrena coitana as a possible host, and this relationship may exist in the British Isles.
Schmid-Egger et al. (1995) and Scheuchl (1995) also suggest that Andrena fuscipes may be a possible host and Venne & Bleidoorn cite A. denticulata. All host data summarised in Smit (2018)
