Bee Exoskeleton and Setae
We're so close you can't even tell this is a Western honey bee. This is actually the exoskeleton of the bee species Apis mellifera. This species is only one of four that are classified as honey bees. There are about 20,000 species of bees in the Order Hymenoptera. This scanning electron micrograph magnifies the hard shell and setae at about 185 times. Setae are small hairs found across the surface of many insects. They aren't hairs like the ones on your head. They act as sensors that determine wind speed, detect chemicals in the air, and help bees collect pollen.
