| scientific name Hyalophora euryalus (Bdv.) common name Ceanothus Silkmoth habitat There are no known native populations in AB. See remarks under "Range". identification This 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. life history Overwintering cocoons of H. euryalus are attached to the larval host plant and occasionally other plants. conservation Not applicable for Alberta. diet info Larvae are reported to feed on a variety of shrubs including Red Alder (Alnus rubra) (which occurs only along the west coast of BC), willow, wild rose, Currants and gooseberries (Ribes spp.), buffaloberry (Sheperdia canadensis), Mountain Maple (Acer glabrum), Saskatoon (Amelanchier alnifolia), and Redstem Ceanothus (Ceanothus sanguineus). Larvae also occasionally feed on Douglas Fir (Pseudotsuga menziesii). range 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. quick link http://entomology.museums.ualberta.ca/searching_species_details.php?s=266

My husband found a moth that looks like this but slightly more brown. It looks like the same markings. It was in Washington State just north of Poulsbo. Is that possible?
