Gomphus flavipes, the river clubtail or yellow-legged dragonfly, is a species of dragonfly in the family Gomphidae. It is found in Europe. Its natural habitat are rivers and large streams. The dragonfly flies from June to September depending on the location.
Gomphus flavipes is a European species. It has the biggest geographical range among the European Gomphid species, occurring from France to eastern Siberia. The species has a very patchy occurrence in Central Europe and has become rare in Western Europe. The southernmost occurrence is known from Greece. In Southern Europe G. flavipes is replaced by other Gomphid species. However, the exact geographical range of the species is still unclear.
Gomphus flavipes lives along the middle and lower reaches of slow flowing medium-sized and big rivers The species prefers riverbed with mud, clay, loam or fine sand as soil, since larvae develop buried in the soil, but avoids areas with decomposition of organic matter and oxygen-poor stagnant water. Reaches with high drift and coarse substrate are also avoided, however, occasionally G. flavipes can be found in bigger lakes with high oxygen content... Wikipedia →
