Red-veined Darter is a widespread and common insect across southern Europe, Africa and Asia. Migration often occurs northwards outside these areas, and is some years it can occur in Britain in good numbers; breeding has occurred as many sites elsewhere in Britain, in some cases leading to the dragonfly becoming established for several years in succession.
