Tobias' caddisfly (Hydropsyche tobiasi) was a caddisfly which lived on the River Rhine between Mainz and Cologne. It was last seen in 1938 and was described in 1977 by Austrian entomologist Heinz Malicky on the basis of material he found in earlier collections. Very little is known about the species and no larvae were ever found. The reason for its extinction might the industrial and urban pollution of the River Rhine.
