There is notable variability in adult markings in both flavilinguis and bimaculata (including extent of white markings on hindwings and tegulae), and this variation seems to become even greater in material from Mexico where the two species are sympatric. The CO-I sequence has been definitive and reliable in separating the two species in all specimens we have sequenced. Both species occur side by side in the Huachucas based on larval collections from near the site of this observation, so by known distribution, both could be expected to be present there. From the adult image here, I would strongly lean to this being A. flavilinguis based not only on the shape of the innermost white spot on the forewing, but also by the clear presence of a blue patch near the trailing edge/hindmargin of the forewing (about 2/3 of the way towards the outer margin). This adult strongly resembles adults of sequenced flavilinguis I have collected from Sierra and Grant Counties in SW NM.

I would have guessed bimaculata. Note white spot on tegula.
