The red-veined darter or nomad (''Sympetrum fonscolombii'') is a dragonfly of the genus ''Sympetrum''. It is a common species in southern Europe and from the 1990s onwards has increasingly been found in northwest Europe, including Britain and Ireland. Its name is sometimes spelt ''fonscolombei'' instead of ''fonscolombii'' but Askew (2004) gives the latter as the correct spelling. There is genetic and behavioural evidence that ''S. fonscolombii'' is not closely related to the other members of the ''Sympetrum'' genus and will at some time in the future be removed from this genus. ==Identification== ''S. fonscolombii'' is similar to other ''Sympetrum'' species but a good view with binoculars should give a positive identification, especially with a male. Males have a red abdomen, redder than many other ''Sympetrum'' species. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma are pale with a border of black veins and the underside of the eye is blue/grey. The female is similar but the abdomen is yellow, not red, and the wings have yellow veins, not red veins as found in the males. The legs of both sexes are mostly black with some yellow. Immature males are like females but often with more red. Male ''S. fonscolombii'' can be mistaken for ''Crocothemis erythraea'' as both are very red dragonflies with yellow bases to the wings, red veins and pale pterostigma. However ''C. erythraea'' has no black on the legs, a broader body and no black on the head. Also ''C. erythraea'' females do not oviposit in tandem. The jizz of these two species is different and with some experience are easy to tell apart.
