Flight period
Univoltine. Males are found during May and June, and rarely in July. Females occur mainly during June, often during May and July, or more rarely in April and August.
Flowers visited
Thyme is the only plant recorded.
Parasitic biology
Cleptoparasitic on bees of the genus Osmia (O. bicornis (Linnaeus), O. leaiana (Kirby) and O. aurulenta (Panzer), O. caerulescens (Linnaeus) (Else, in prep.)) and Chelostoma. The female enters the nest of the host and lays an egg on or near the egg of the host. Gauld and Bolton (1988) indicate that the sting is used to penetrate the cell wall, thus acting as an ovipositor. P Westrich (pers.com., 1999) says that the egg is placed directly in the cell. On hatching, the first instar larva, which has large mandibles, eats the egg of the host. Later instars have smaller mandibles and feed on the stored food of the host.

As you can see not many Recorded sightings in East Anglia but this is probably just due to under recording or the NBN map not being updated.
