Large-eyed Bee

This is a male bumble bee. There are a few species, including the one shown here (Bombus nevadensis), that are unusual in having very large eyes — so large in fact that they take up most of the face. Why they are so large in some bumble bees but not others is not known, but it probably has to do with differing strategies in finding females to mate with.

An interesting fact about male bees and wasps is that they do not have fathers; they develop from unfertilized eggs from their mother and as a result, they have half of the genetic makeup of their mother, sisters and daughters.
