Fur. I think of it as hair, but fair enough. The fur on a bee is vital to its survival. Virtually all bees have branched hairs somewhere on their bodies. In fact, the presence of those branched hairs is one of the major ways bees can be distinguished from other insects.
Bees are vegetarians. They collect nectar from flowers for their energy needs, but they also collect pollen which supplies themand their youngwith protein, lipids, and nutrients. As a bees goes from flower to flower, pollen grains get caught in the branched hairs, which facilitates their collection by the bees. Bees carry pollen in different ways, but a honey bee uses her hairy front and middle legs like brushes to comb the pollen off her body and pack it into hairy recesses on her rear legs. These hairy recesses are called pollen baskets or corbiculae.
Thanks to hairy . . . or furry . . . bodies, the bees inadvertently leave some of the pollen grains behind each time they visit another flower, which is the primary mechanism of insect pollination. Without those furry bodies flitting from flower to flower, life on earth would be very different indeed.
