Cleptoparasitic: Hosts; A cleptoparasite of both Andrena apicata (e.g. R.C.L. Perkins, 1919g, 1943, 1945; Chambers, 1949) and A. clarkella (numerous references, including R.C.L. Perkins, 1919g). On one occasion in Hampshire, a female of A. clarkella was observed to fill in its nest entrance (between the buttress roots of a tree) with excavated soil. While this was taking place, two females of Nomada leucophthalma were noted at rest on the base of the tree a short distance away from, and facing the burrow. As soon as the nest's owner had flown away, one Nomada alighted at the nest entrance, and immediately began to burrow into it, soon disappearing from view (G.R. Else, in litt.).
German authors also cite A. nycthemera as a possible host (cited in Smit, 2018)
