There are about 1,000 species of sweat bees in the United States, Canada and Central America, including 44 species in Florida alone. These bees enjoy one strange thing: human sweat. Fortunately, they are not aggressive, and will only sting if pressed against the skin.

Studies of the similarity of the DNA in wasps and bees suggest that the first bees evolved from wasps in the family Crabronidae about 130 million years ago, 50 million years before the first known fossil bee, and probably very shortly after the first flowers evolved in the Cretaceous period.

A honey bee can fly at speeds of 15 mph and beat its wings 200 times per second.

Leafcutter bees nest in soft, rotted wood or in the stems of large, pithy plants, such as roses. They use cut leaf fragments to construct their nest cells.

The queen is busiest in the summer months, when she can lay up to 2,500 eggs a day.
