A univoltine species; mid June to late August or the beginning of September (Else & Edwards, 2018; Stanisavljevic, 2000).
Parasites and predators F. Smith (1876) gives Coelioxys elongata as a cleptoparasite, but this requires confirmation. In mainland Europe, C. alata may also be a cleptoparasite (Banaszak & Romasenko, 1998; Bogusch, 2005)), as may C. lanceolata (Peeters, Raemakers & Smit, 1999 ).
