Biology:
Rabaglia et al. 2006: This species has a limited native distribution of Japan and Eastern Russia, but it has recently been introduced into several European countries and North America. It was first detected in western North America in the late 1990s (Mudge et al. 2001) and recently reported in several eastern states (Hoebeke and Rabaglia 2006). It is similar in appearance to X. saxesenii, but can be distinguished by the larger size, and the larger, more pointed and hooked tubercules on the declivity (Holzschuh 1994).
