Blera robusta

Species of fly

Blera robusta, the greenish wood fly, is a rare species of syrphid fly first officially described by Curran in 1922. Hoverflies get this name from the ability to remain nearly motionless while in flight. The adults are also known as flower flies, for they are commonly found around and on the flowers from which they get both energy-giving nectar and protein rich pollen. The larvae are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
