The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located Such 'Invasion Years' occurred in 1906, 1926, 1945, 1953, and 1995.

An almost unmistakable darter, red-bodied in the male, with both sexes having large amounts of saffron-yellow colouration to the basal area of each wing, which is particularly noticeable on the hind-wings. Other Sympetrum species may have limited yellow-orange colouration near the extreme wing-bases, especially in females, but never so extensively as in this species.
Sites which are likely to attract this species have thick rushy margins. The Yellow-winged Darter tends to make quite short flights when settled at a site, and frequently perches quite low down on vegetation.
The Yellow-winged Darter has bred but is not established in the UK. It has occurred in Cumbria as single individuals on very few occasions. The most recent record was at Killington Reservoir in August 1995.
