''Sympetrum danae'', the black darter or black meadowhawk is a dragonfly found in northern Europe, Asia, and North America. At about long, it is Britain's smallest resident dragonfly. It is a very active late summer insect typical of heathland and moorland bog pools. Members of the genus ''Sympetrum'' are known as darters in the UK and as meadowhawks in the US and Canada. ==Identification== Both sexes have black legs and pterostigmata and a very broad base to the hind wing. The thorax has yellow sides separated by a bold black panel in which are three yellow spots, resembling a highland darter (''Sympetrum nigrescens''). The male has a mainly black thorax and abdomen. The abdomen has small yellow marks on the side, that darken with age. The wings are clear. The female has black legs and brown eyes. The abdomen is mainly yellow, becoming browner with age. It has small yellow patches at the wing bases. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sympetrum danae」の詳細全文を読む スポンサード リンク
