The larvae are borers in the stems and roots of the hosts. The life-cycle requires two years to complete, with the moth overwintering twice in the larval stage. They pupate in the spring of the third year, and emerge shortly thereafter. The adults are diurnal, but are rarely seen.
Diet Info The larval host is species of poplar, and to a lesser extent willows. They appear to prefer stressed of damaged host trees. Range
Widespread in western North America, east at least across the Prairie Provinces, and south to California and Arizona. In Alberta it has been collected mainly in the foothills and parklands, but likely occurs…
Widespread in western North America, east at least across the Prairie Provinces, and south to California and Arizona. In Alberta it has been collected mainly in the foothills and parklands, but likely occurs throughout the wooded parts of the province, wherever hardwoods are present. It has been recorded in adjacent Saskatchewan in both the arid Grasslands National Park area and at Uranium City.
Notes Also called the American Hornet Moth (Wong and Ives, 1988). It is rarely encountered unless baited with synthetic pheromones.
