Bee diversity (Hymenoptera: Apoidea) visiting Broad Bean (Vicia faba L.) flowers in Egypt

Different bee flower visitors were observed during the flowering seasons of Broad Bean in Ismailia, eastern Egypt, the Nile Delta and Alexandria, western Egypt. Eight major bee visitors were observed: Andrena ovatula (Kirby, 1802), Andrena sp. (Andrenidae), Chalicodoma siculum (Rossi, 1792) (Megachilidae), Colletes lacunatus Dours, 1872 (Colletidae), Apis mellifera Linnaeus, 1758, Anthophora hispanica (Fabricius, 1787), A. aegyptiaca (Dalla Torre and Friese, 1895) and Xylocopa pubescens (Spinola, 1838) (Apidae). Anthophora hispanica and A. aegyptiaca as well as Chalicodoma siculum had their peak flying period in the middle of the flowering season of the Broad Bean, while Xylocopa pubescens and Andrena sp. had their peak period in the second half of the flowering period.
