Southwestern Naturalist 38 3, 252-274. Discussed as Ironopsis grandis Quote from page 261: "The first author has seen specimens from Idaho, Washington, and Wyoming. This species was therefore to be expected in Colorado. It is suprising that the disctinctive larvae of this species had not been reported before in any of the state ecological studies, and it may be that populations are very isolated, such as those of the Black Hills, South Dakota (McCafferty, 1990).
