Eggs, larvae and pupae are found in the tunnel system excavated by the female. Beetles breed in host plants from 2 - 30 cm in diameter, although small branches and stems are most commonly attacked. Attacks may occur on apparently healthy, stressed, or freshly cut host material. High humidity is required for successful reproduction. Attacks on living plants usually are near ground level on saplings or at bark wounds on larger trees.
Females remain with their brood until maturity.
Males are rare and flightless. The only control recommended so far is to remove and burn infested plants or plant parts. These applications should be done late in the day in order for drying to occur over night to reduce light and heat breakdown of the product.
