[[top left margin]] RD. Sage 1965 [[top right margin]] 8 Xylocopa sp. [[underlined]] Playa Cocos, sea level, Guanacaste, Costa Rica [[/underlined]] [[left margin]] 11 July 10:50. First bee. large black. Time it took to visit 10 flowers 1 min 15 sec. (caught it.) It forcibly crawled into some of the flowers which were unopened. Examination immediately upon capture showed yellow pollen on abdomen and legs. 11:00 1 bee (large-similar to one just taken). 11:10. Another large bee visiting yellow legume. While trying to count its rate of flower visitation I chanced on a small patch of a blue flower & there was a Schoenherria visiting these tiny flowers. The distance between the two bees was about 10 ft. I don't think the large bee could even land on these small flowers. My impression was that the Schoenherria was a faster flying bee... more like a hover fly. Caught the animal. Examination did not reveal any pollen on this animal. Schoenherria 10 flowers/9 sec. 11:25 " 10 " /10 sec " " 10 " /10 sec " 11:30 1 large black bee working yellow legumes 11:30 3 Shoenherria on blue flowers. 12:00 5 large black bees on yellow legumes.
