Polylectic: Pollen sources have been identified as Rubus, Prunus spinosa (Rosaceae); Heracleum (Apiaceae) Salix and "thistles" (R.C.L. Perkins, 1923 and 1945).
The spring brood (probably referable to A. stragulata) also flies to Salix cinerea, Salix aurita (Salicaceae) and Taraxacum (Asteraceae) and the summer one to Angelica (Apiaceae); Cirsium arvense and Taraxacum (Asteraceae) but it remains to be seen if these are all pollen sources.
Westrich (1987) considers A. eximia (=A. stragulata) to be polylectic, but A. rosae to be oligolectic on Apiaceae.
Males regularly nectar at flowers of Cirsium arvense (Asteraceae) in the Netherlands (J. Visser, pers. comm).
Radchenko (2015). citing others, states that it is a polylectic species. The females visit flowers of different plants. For example, in the Lipetsk region of Russia this species was registered on 28 plant species from 13 families (Kuznetsova 1990). However, females of the first generation prefer flowers of Salix (Salicaceae) and Rosaceae (such as Prunus spinosa, Potentilla verna, Crataegus oxyacantha, R. aureum, Cerasus sp., Malus sp., Rosa sp., Fragaria vesca, etc.) and Ribes grossularia (Grossulariaceae), while the second generation occurs predominantly on flowers of Apiaceae, more rarely on Asteraceae (Osytshnjuk 1977), Campanulaceae (Celary and Wisniowski 2009) and Fabaceae (Tadauchi 2008).
