Abstract
During 20 days in 1985, floral biological observations were made at 1 850-2 100m elevation on Cerro de la Neblina in Venezuela. Heliamphora tatei var. neblinae (Sarraceniaceae) is nectarless and has poricidal anthers. Heliamphora tatei, Graffenrieda fruticosa, G. polymera, G. reticulata, Tocca pachystachya, T. tepuiensis (Melastomataceae), Saxofridericia compressa, and Stegolepsis neblinensis (Rapateaceae), are buzz-pollinated by ten species of Bombus, Eulaema, Melipona, Centris, Xylocopa, Dialictus, and Neocorynura. Additional observations of floral visits on tepui species of Gentianaceae, Loranthaceae, Malpighiaceae, Ericaceae, Orchidaceae, and Asteraceae are reported. Visitors include the hummingbird Campylopterus duidae, the flower-piercer Diglossa duidae, the nectarivorous bat Anoura geoffroyi, and various species of Centris and Bombus bees. Scent baits for euglossine bees attracted very few bees. Apis mellifera adansonii-scutellata, the africanized honey bee, was caught at 1 850m elevation.
