Diagnostic remarks

Stamnodes coenonymphata is highly variable in colour, especially the hindwing underside.The transverse medial band of the hindwing underside common to many Cercocarpus -feeding Stamnodes is generally white in S. coenonymphata with the scales basad and distad greatly differing in colour. The transverse band is more basally positioned than in congeners and has a more acute angle as it extends basad toward the margins. This species is most often confused with S. costimacula , S. annellata , and S. cassinoi .

Distribution

Mexico: Stamnodes coenonymphata is found in the chaparral associations, foothills, canyons, and Pacific coastal scrub communities of northwestern Baja California. USA: the core of this species’ range lies in California.

Biology

The peak flight of S. coenonymphata is January to March with larvae to follow in the spring and early summer. Larvae ( Fig. 91 View Figs 90–93 ) are hosted by birch leaf mountain mahogany ( Cercocarpus betuloides Nutt. ) ( McFarland 1965).

Molecular characterization

This species is represented in BOLD as BIN: BOLD:AAF2593 (n = 26). At present, the average pairwise intraspecific distance is 0.82%, the pairwise maximum intraspecific distance is 1.93%, and the distance to the nearest adjacent interspecific neighbour, Stamnodes formosata (n = 20), is about 3%.
