Cleptoparasitic: Hosts; In Hampshire, C.R. Vardy excavated a female, together with a female Lasioglossum zonulus, from either a hibernaculum or, more likely, an early nest of the latter, at the beginning of April. In the New Forest, Hampshire, Daltry (1952) collected a few specimens of the Sphecodes on Asteraceae flowers along with some L. zonulus, which he considered a possible host. Specimens have been seen flying with the same Lasioglossum in both Hampshire and Dorset (pers. obs.). R.C.L. Perkins (1917) considered Halictus eurygnathus [as H. quadricinctus] as a possible host, but gave no supporting evidence (Else & Edwards, 2018).
