CENTRAL FLORIDA CRITTER OF THE DAY: Syrphid Fly (Palpada sp. likely agrorum)

New species for me.  This one is considerably smaller than others I have seen in the genus.

They are Bee mimics.  Other common names: hover fly; flower fly

As a member of the Tribe Eristalini  the larvae live in organic rich water.
