Cleptoparasitic: Hosts; A number of host species have been listed in Smit (2018). In detail: Andrena minutula ond other species in the subgenus Micrandrena. R.C.L. Perkins (1919g) lists A. minutula, A. subopaca, A. semilaevis [as A. saundersella] and A. falsifica as host species. In Dorset, G.M. Spooner (pers. comm.) observed the species at the burrows of A. alfkenella. Gardner (1901c) cites A. wilkella as a host, but this seems unlikely in view of the latter's much larger size.
In Germany and Poland, A. minutuloides is cited as an additional host. (Stöckhert, 1933; Celary, 1995)
