Video-Bee gathering oil from orchid
- The orchid-pollination videos on Youtube get better and better and must be sampled when you have the opportunity. Go to this site and your can watch a female in the genus Tetrapedia gather oil from the flowers of an orchid in the genus Trichocentrum (used to be in Oncidium). The tumor-like callus on the lip petal (labellum) contains oileries (elaiophores) instead of nectaries. These bees have "oil vials" on their hind legs. The larvae are fed pollen and whipped up oil (must be like being breast fed mayonnaise).
