Taphrorychus bicolor (Herbst, 1793)

Distribution in Iran. East Azarbaijan ( Samin et al. 2011), Tehran and other northern provinces ( Modarres Awal 1997 as Taphrorynchus [sic] alni ). The occurrence of this species in Iran needs further confirmation, as it may have been confused with T. lenkoranus Reitter (see below).

General distribution. Europe, Turkey, Caucasus. The inclusion of Korea in the distribution ( Knížek 2011) is perhaps the result of misidentification or introduction.

Biology. This species usually breeds in trees of the families Betulaceae and Fagaceae . Recorded in Iran from Carpinus betulus (Betulaceae) , Fagus orientalis , Quercus sp. ( Fagaceae ), Juglans regia (Juglandaceae) , Pyrus communis (Rosaceae) ( Modarres Awal 1997; Samin et al. 2011). The biology and gallery system have been described by Palm (1959), and Schönherr and Krautwurst (1979). Francke et al. (1995) discuss the components of the male aggregation pheromone. Dippel et al. (1997) discuss the role of predation in reducing population densities.
