Length: 63mm

A small Hawker, not aggressive towards other individuals and occasionally seen in large feeding swarms. It flies late into the autumn and is likely to be the only Hawker found in November. The costa is brown and there is a “golf-tee” shaped, yellow mark on S2. The male looks quite dark with blue, paired spots along the abdomen. The pale yellow ante-humerals are indistinct and short and eyes are blue.
The female is brown with similar markings to the male but the spots are smaller and often yellow, occasionally blue. The ante-humerals are insignificant or absent and eyes are brownish.

A relatively new arrival to the UK. In the 1940′s this dragonfly was only a migrant but a small colony established in the South East from which individuals have spread. It can now be found well into Northern England. Numbers are boosted during the summer by migrants crossing the channel in the South East.
