Bees say “hello” with their antennae

Just like humans use both sides of their brain for different purposes, so too do honeybees. In fact, they prefer to use their right-hand antenna when determining the difference between friend and foe. Each antenna is covered in sensitive hairs called sensilla, which are the chemical receptors that send sensory information to the brain. The right antenna apparently features more sensilla that are concerned with the sense of smell, which is an important method of insect communication.
