Abstract - The nightly resting behaviour of some solitary bees (Epeolus, Triepeolus, Protepeolus, Anthophora, and Melecta) was studied in the laboratory and compared with results obtained previously in honey bees. Similarities and differences in physiological and behavioural correlates of rest were found; only honey bees exhibit marked amounts of antennal motility.

Key words: Apoidea / solitary bee / Apis mellifera / rest at night / sleep / behavioural physiology
