On the left and below you can see an SEM image
of the entire antenna of a worker, with the long scape, roundish pedicel followed by 10 smaller
segments that make up the flagellum, the worker and queen antennae are the same, but the male has 11 segments in his flagellum.
Taste and smell are conveyed to the bee through the tiny hairs on the antenna and mouthparts. The scent molecules pass through the tiny pores on the pore plates (see below), then stick to receptor sites on the sensory cells. The pore plates are also involved in the sense of smell.
It is the great good fortune of humans that, by an accident of evolution, we and bees find the same scents attractive.
