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.
