boreal conifers
Dasysyrphus laticaudus, the boreal conifer fly, is a common species of syrphid fly observed in Eastern and Northern North America. 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. The larvae of this genus are aphid predators. .
