Cruz in Rosario, and Bah-bah in Prosperidad). Aerial net sweeps revealed two hymenopterans, Apis dorsata and Polistes sp., as the most predominant flower visitors. A. dorsata was also found to carry more pollen per individual followed by Polistes sp. and dipterans. Quantity of pollen colleted from A. dorsata did not vary significantly with places of collection. A bumble bee (Bombus sp.) was the largest winged insect capture and obviously, can carry the most pollens.
