Bee Mimic Flies

I recently photographed two flies that are obviously bee mimics.  They both look like bees–one a honeybee and the other a bumblebee.  Both sort of pump their abdomens–sending a not so subtle message that they have a stinger and are not afraid to use it.  Of course, it is all bluff.

The bumblebee mimic is Eristalis anthophorina.

It really does look like a medium-sized bumblebee.  Even the back leg is enlarged like the pollen basket of a bumblebee.

The other fly is called a drone fly–Eristalis tenix.  This is a very early non-native import into North America.  It mimics the non-native honeybee.
