N.J. Vereecken (pers. comm) has observed this species foraging for pollen at flowers of Limodorum abortivum (Orchidaceae). This is a very unusual observation of orchid pollen being collected as forage.
Pauly (in litt. ) lists Sonchus asper Asteraceae as a forage plant in Greece, and Sinapis arvensis (Brassicaceae) in Algeria.
