Eristalis cryptarum : ウィキペディア英語版 | Eristalis cryptarum
''Eristalis cryptarum'' is a European species of hoverfly. Known as the bog hoverfly, it only lives in and around wet heathland and valley mires. Its larvae are assumed to live in peat that is saturated with water, such as that found in these boggy areas.〔(【引用サイトリンク】title=Action plan for Eristalis cryptarum )〕 The hoverfly has a wide distribution across central and northern Europe, including Siberia. 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.〔 ==References==
