Green orchid bee

A male mixes his own perfume from plant smells and fans it with his wings to attract a female.

It arrived in Florida by accident, maybe hiding in a wooden pallet, and was first spotted there in 2003.

The mother builds her nest out of sticky plant resin and lays one egg in each of up to twenty little rooms.

At first scientists thought it was a different bee. They had to look closely at the tiny teeth on the males' jaws to tell them apart.

Its very long tongue lets it reach nectar deep inside long, tube-shaped flowers.
