Most animal-pollinated flowers offer nectar or pollen as a reward to their pollinators. A small fraction, however, have switched to other rewards, such as fatty oils offered in glandular hairs or just below the epidermis. This type of reward has evolved in some 150 genera in at least 11 families, including South American and African Orchidaceae [1,2]. Oiloffering flowers are exploited by a few hundred species of oil-collecting bees in temperate and tropical biomes on all continents except Antarctica [1,2]. Oil bees depend obligatorily on floral oil for cell lining and as larval food [3,4], which is why oil collecting usually is confined to female bees.
