Archived specimens of Dreissena, collected as part of a long-term biomonitoring effort in the lower Don and Volga River systems and dating back to 1979, were re-examined. Originally identified as Dreissena polymorpha or variants thereof, some of the specimens were identified to be Dreissena bugensis. Based on this new evidence, the invasion history of D. bugensis in these two river systems was re-evaluated. The finding of D. bugensis in the lower Volga River in the early 1980s rather than in the late 1980s/early 1990s indicates that its spread was much slower than earlier believed. Apparently, widespread dispersal was greatly facilitated by the completion of the reservoir system in the Volga River in the late 1980s which created conditions that were more conducive to this species. Upstream dispersal in both the Don and Volga Rivers was likely a function of human-mediated transport.
