Cucullia obscurior. This taxon had been treated as a western subspecies of C. florea because western specimens generally lack the reddish-gray shading along the forewing costa. Poole (1995) treated C. obscurior as a valid species because specimens matching the C. florea and C. obscurior phenotypes were found to occur together in areas of Washington and Utah. In spite of these phenotypes occurring together in these two areas, the variability of this character in other areas of the west make it very difficult to assign many specimens to one name or the other, so specimens with an entirely gray forewing are treated as a form of C. florea (= C. obscurior, syn. n.).
