Nesting site and nesting material are unknown. However, Haetosmia possibly nests in excavated burrows in sandy soil as indicated by the following observations: all three species seem to be restricted to sandy ground (Mavromoustakis, 1954b for Haetosmia vechti; A. Müller and C. Sedivy, personal observation for H. circumventa; C. Praz, personal observation for H. brachyura); in addition, the females possess long bristles on tibia and tarsus of their forelegs, which are possibly used to flip away sand during nest excavation in the ground.
