Common NameCeanothus Silkmoth IdentificationThis species can be recognized by the pinkish maroon colour that prevails beyond the postmedian white band. In H. columbia gloveri, this outer third of the wing has very little or no trace of maroon. Although variable, the discal spots are usually greatly elongated towards the outer edge of the wing, and this trait distinguishes euryalus from the other species of Hyalophora. The range of euryalus is not known to overlap with any other Hyalophora in Canada.

The Ceanothus Silkmoth occurs in the dry intermontane valleys and interior of BC (as far north as Prince George along the Fraser River) south to Baja California. The only AB record of this species is for a live specimen introduced along with a shipment of ornamental shrubs from Oregon to Red Deer (E. Mengersen, pers. comm.). There is a small possibility this species is present in the Waterton / Castle River area of AB.
