A univoltine species with an extended flight period. The overwintering females emerge at the beginning of April, and the males appear in late July.
Label data from a single Spanish specimen shows that females are active in (at least) May (Ortiz-Sanchez & Pauly, 2017).
Parasites: The bee Nomada sheppardana is cited as a cleptoparasite of this species (Haesler 1982; Vegter 1971).
