In addition, arborvitae have been popular, in part, because they have few insect and disease pests. The antennae of the male are slightly longer than his body. The antennae are about three-fourths of the length of her body. There has been no specific research on control of this beetle as it had not been thought to be a pest. The Experiment Station plans to investigate the natural history of this insect and to test various insecticides to see if they are effective.
Adults probably fly in early spring.
It is not know when they mate or lay eggs. When eggs hatch, the larvae burrow into the phloem and cambium just under the bark and feed. No damage is visible at this time. In late summer, the larvae burrow into the sapwood and pupate. The pupae develop into adults, which remain in the wood during the winter.
