Platycheirus islandicus

Platycheirus islandicus is a species of syrphid fly in the hoverfly family Syrphidae. It has occasionally been identified as a synonym of the closely related Platycheirus peltatus but several authorities offer it full species status, and it has been recognized as vulnerable by the IUCN.[1] It is one of the few species recognized as endemic to Iceland.[3] Within Iceland, the species is typically found in birch forests but it may also occur in meadows and on beaches. It can be seen between June and August.
