We observed the mating behavior of Monochamus saltuarius (Cerambycidae: Lamiinae) and confirmed the following behavioral actions. The male reacted to the female with his antennae or tarsi, the male dashed to the female and mounted her back. Copulation consisted of three phases: First, while bending at the abdomen, the male inserted his penis into the female's genitalia, second, the male is motionless with the females genitalia being pulled out from her abdomen by the males penis, outside of both body cavities, finally, the male tries to pull out his penis from the female genitalia. The copulation was shown to take place mostly for one and a half minutes, with a significant tendency to be slightly shortened as the pair progressed from the first through the third copulation. The violent fight between two males took place in the presence of a female and sometimes she changed her mate. The male did not differentiate between dead and live females, because the male mounted dead females as same as live them.
