OBSERVATIONS ON THE NESTS AND BEHAVIOUR OF SOME EURYGLOSSINE BEES (HYMENOPTERA: COLLETIDAE)

Abstract

Nests of Euryglossa (Euryglossa) sp., Euryglossula chalcosoma (Cockerell), Brachyhesma perlutea (Cockerell), Xanthesma sp., Xanthesma furcifera (Cockerell), Euryglossina (Eury‐glossina) hypochroma Cockerell, Euryglossina (Turnerella) pulchra Exley, Pachyprosopis haematostoma Cockerell and Pachyprosopis indicans Cockerell are described for the first time. Euryglossina (Turnerella) pulchra appears to be parasitised by a species of Gasteruption (Hymenoptera: Gasteruptiidae) and Euryglossula chalcosoma and Xanthesma furcifera by species of Hyptiogaster (Hymenoptera: Gasteruptiidae). Males of Euryglossa (Euhesma) sp. and Euryglossa (Callohesma) sp. were found sleeping on low vegetation. Males of Euryglossina (Euryglossina) hypochroma spent nights and cool periods within the nests. Copyright © 1969, Wiley Blackwell. All rights reserved
