It is found in northern Europe, Asia, and North America. This darter is restricted to acidic shallow pools, lake margins and ditches in lowland heath and moorland bogs, usually with bog-mosses and rushes. Eggs are laid in flight by dipping the tip of the abdomen into the water. The eggs hatch the following spring and the larvae develop very rapidly, emerging after as little as two months.
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. 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.
Kūno ilgis siekia 35 mm, o išskleisti sparnai – 60 mm ilgio. Abiejų lyčių individų išvaizda kiek skiriasi: patinų pilveliai yra juodos, o patelių – rusvos spalvos. Juosvosios skėtės arealas apima Europą ir Aziją.‥
