This species overwinters as young adults. The young adults will emerge as the first wave of adults between May and June. A second wave consisting of the overwintering larvae and the adults that have already mated will have their flight period between July and August. The females will find an appropriate new host and begin to excavate a gallery from a bark crevice. The male will then join the female to mate. After mating the male may or may not leave the female. Galleries are approximately 12 to 30 cm long and follow the grain of the wood on the inner bark. Oviposition will begin 2 to 3 days after the attack and it is estimated that up to 160 eggs can be found per gallery. Frass is packed to separate the eggs as no egg niches are excavated. The eggs will incubate for between 8 to 24 days. The larvae will then hatch and excavate individual mines for between 19 to 72 days. The larvae then pupate for 5 to 18 days. The young adults that emerge after pupation will then overwinter.
