This is a cleptoparasitic species, so no pollen is gathered.
A cleptoparasite of several Colletes species: C. daviesanus (Blair 1920; Carr 1916; Chambers 1949; Richards 1937, 1979), C. fodiens (Chambers 1949; Hallett 1928; Perkins 1920, 1924; Richards 1937, 1979), C. halophilus (Guichard 1974) and C. succinctus (Clark 1924; Butterfield & Fordham 1932; O’Toole & Raw 1991). However, there are very few rearing records and some of the above hosts have yet to be confirmed. The Scottish record from Torrs Warren, Wigtownshire (see map), was almost certainly attacking C. fodiens, though C. floralis was also present and in, apparently, greater numbers…. BWARS
Throughout much of Britain and the Channel Islands, becoming scarce in northern England. There is a single confirmed record from the Isle of Man and one from south-west Scotland, but none from Ireland. Often locally common.
