Distribution
Food
Life cycle
They spend winter as mature larvae or pupae in tunnels just under the bark of the tree, with adults emerging in late spring (May in the northern hemisphere). The females fly to susceptible trees where they bore into the cambium, laying eggs in pockets along the tunnel walls. Second-generation adults emerge in summer (mid-August in the northern hemisphere). There may be two or even three generations in a year.[3]
