Sphaerophoria sp.

Flower Fly / Hover Fly


Sphaerophoria sp., family Syrphidae, Hover Flies

 

Family: Syrphidae

Subfamily: Syrphinae

 

 

Yokoi and Fujisaki (2009) described a "hesitation behavior" of Sphaerophoria spp. flies that was not present in several other species of Syrphid they observed, nor in bee species they studied. This behavior consisted of "moving backwards and forwards in front of a flower," possibly assessing the risk of predation, before deciding whether to light there and begin foraging.
