Callicera erratica

Callicera erratica  ( Walker, 1849 ), the Golden Pine Fly , is a rare species of syrphid fly observed in the Northeastern United States and Canada. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae live in water filled ratholes and cavities of old living conifers.
