Excavator: Ground. Banks and vertical earth faces. This species seems to normally nest in small, rather compact aggregations, these having been observed in an open, steep, sandy slope, in the soil adhering to the roots of a fallen tree in woodland (both personal observations), and in the exposed soil of a hedge bank (G.M. Spooner, pers. comm.).
An Italian nest has been described and figured by Bonelli (1954a)[cited as H. minutus].
Probably a solitary species (Westrich, 1989).
