Bee Antennae Offer Links between the Evolution of Social Behavior and Communication (IMAGE)
Caption
As bees' social behavior evolved, their complex chemical communication systems evolved in concert. An international team of researchers, including those from Princeton University, reported that a certain species of bees, called halictid bees, have more sensorial machinery compared with related solitary species. The difference is measured by the density of tiny, hollow sensory hairs called sensilla on their antennae.
