A worker bee is a non-reproducing female which performs certain tasks in support of a bee hive. Worker bees undergo a well defined progression of capabilities. In the summer 98% of the bees in a hive are worker bees. In the winter, besides the queen, all bees are worker bees. Workers feed the queen and larvae, guard the hive entrance and help to keep the hive cool by fanning their wings. Worker bees also collect nectar to make honey. In addition, honey bees produce wax comb.
