Welcome to the Twelve Days of Honey Bees: Day 2. A honey bee has two antennae.
The antennae is the primary sensory organ for a bee, providing touch, smell, hearing, and taste all in two slender stalks. Each antenna is attached to the head in a bowl-like socket, followed by three main parts called the scape, the pedicel, and the flagellum.
A detailed discussed of honey bee antennae can be found at the American Bee Journal.
The antennae is also one method of distinguishing a bee from a fly. Flies tend to have short antennae while bees have longer ones. Hover flies, especially, are often mistaken for bees. As you can see from the below image of a hover fly, the antennae are rather short.
By contrast, the below image of a foraging honey bee on a dandelion clearly shows her long antennae.
May you prosper and find honey.
