Similar to other Chrysobothris species, in that adults oviposit into cracks and crevices on the bark. larvae hatch out, boring into the bark, feeding on the phloem and outer sapwood. Larvae over-winter in pupal cells constructed in the outer wood, pupating in the following spring and emerging as adults in early summer. In southern climates the life cycle takes one year. Bright (1987) suggests a longer development time in Canada.
Conservation
Uncommon.
Diet Info
Hosts include a wide variety of deciduous trees, including maple, poplar and willow (Fisher 1942, Bright 1987). In Alberta the adults have been associated with aspen.
Range
These beetles are found from British Columbia to New Brunswick and south to Mexico (Fisher 1942, Bright 1987).
