The time necessary for this insect to complete its life cycle is unknown but reasoning from analogy, it seems probable that it is two and possibly three years. The larvae that are to transform to beetles in one season change to pupae sometime about the middle of May or earlier, and the beetles begin to appear the latter part of that month and continue to emerge for some time, examples having been taken as late as August 24. The eggs are deposited upon the bark in June,.
