Biology. This species usually breeds in Fagaceae ( Castanea , Fagus , Quercus ) ( Pfeffer 1995), but sometimes also in trees of other families including Betulaceae , Rosaceae , Sapindaceae , Ulmaceae ( Stark 1952) . Recorded in Iran from Castanea sativa , Fagus orientalis , Quercus sp. ( Fagaceae ), sometimes on Carpinus betulus (Betulaceae) , Laurus nobilis (Lauraceae) , Cerasus avium , Mespilus germanica (Rosaceae) , Acer sp. ( Sapindaceae ), Tilia begonifolia (Tiliaceae) , Ulmus spp . ( Ulmaceae ) ( Modarres Awal 1997). The gallery system is typical of the genus with the entrance tunnel leading to branched galleries, usually in one transverse plane, extending deep into the wood, and without enlargements ( Balachowsky 1949; Lombardero 1996). The larvae live freely in the galleries and eventually pupate there, the new generation of adults emerging through the original entrance hole. The predominant ambrosia fungus is the same as that of Platypus cylindrus and Xyleborus monographus ( Gebhardt et al. 2004) .
