$Tot 50-55mm, Ab, 37-42mm, Hw 30-35mm.\nIdentification:\nThe characters of this clubtail are rather different . It prefers very large (lowland) rivers and may easily be overlooked. Populations can best be found by searching for exuviae on river banks.\nOccurrence:\nA north Asian species, with western outposts in large rivers such as the Rhine, Loire and Po. Common in large lowland rivers in eastern Europe, but staged a strong comeback in Western Europe in the 1990s. Now abundant in rivers such as the Rhine, Elbe and Danube, right down to their estuaries.\nHabitat:\nSlow flowing lower sections of large rivers with sandy beds. Larvae burrow shallowly in fine substrates with relatively high concentrations of organic matter.\nFlight Season:\nLate and protracted, compared with other Gomphus species, from early June to early October, with maximum emergence in June and July.\n\nThis is a scarce Gomphus Species along the large Dutch Rivers. This Picture is made along the River Waal, near “Slot Loevestein” in the Province of Gelderland.$
