Chalcosyrphus (Xylotomima) nemorum , the Dusky-banded Leafwalker, is a common species of syrphid fly with a Palearctic and Nearctic distribution. Hoverflies get their names 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 flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae have been found under the bark of Larix, Pinus and a variety of hardwoods.
Eristalis cryptarum is a holarctic species of hoverfly. Known as the bog hoverfly or bog-dwelling drone fly, it is a bog specialist but may occur in other wetlands. Its larvae are assumed to live in peat that is saturated with water, such as that found in these boggy areas. The female has been observed depositing eggs on and close to very fresh cow dung along oligotrophic seepages in moorland.

Paragus haemorrhous,the Black-backed Grass Skimmer is a common widespread species of hoverfly found in many parts of Europe, Africa and the Nearctic. 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 are predators on aphids.
