rdf:langString 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. Hoverflies get their names from the ability to remain nearly motionless while in flight The adults, also know as flower flies for they are commonly found around and on flowers from which they get both energy-giving nectar and protein rich pollen. . The larvae are aquatic filter-feeders of the rat-tailed type. E. cryptarum has a wide distribution across central and Northern Europe and East to Siberia and Mongolia. In England, it was once found in all southwestern counties as far east as the New Forest, but since the middle of the 20th century its range has contracted, for unknown reasons, and it is only now found at a few sites on Dartmoor, Devon. In Denmark it is considered critically endangered, possibly extinct.
