Spalding's Quaker is one of the least commonly collected Alberta Quaker's. Here at least it is a moth of the dry prairie grasslands region, absent from the cooler parklands and foothills. The earlier collectors apparently missed Spalding's Quaker; the first specimens were collected in and near Olds in 1998 by Ernest Mengersen and his students. Since then we have picked up the occasional specimen along the lower Red Deer River and Milk River valley.
