Abstract

Floral visitors of Rafflesia lagascae Blanco are identified and recorded as actual or potential pollinators. The most commonly observed was the metallic blue blow fly, Chrysomya megacephala (Fabricius), while two other blow flies, observed but not collected include a dull-colored, bristly species that probably belongs to Bengalia, and the greenish-blue species Lucilia fumicosta Malloch. The red-eyed flesh fly, Sarcophaga sp., was also observed to visit and possibly larviposits some of its tiny maggots into the perigone. The common housefly, Musca domestica L., vinegar flies Drosophila spp., and undetermined dolichopodids and phorids were also observed. The phorids probably play a greater role toward the decay of the more matured flowers. Video-documentation and other field studies are recommended for this threatened Rafflesia species in a forest reserve that has witnessed a recent rise in tourist visits.
