Ponometia huita

Ponometia huita is most likely to be confused with binocula. The large, dark patch in the outer half of the forewing of binocula is narrower than in huita. In addition the dark area of binocula has a narrow, white, squiggley line in the position of the subterminal line and lacks a pair of light gray, roughly triangular patches outlined with white near the postmedial line. In contrast huita has the light gray triangles and lacks a white, squiggley subterminal line.

Ponometia virginalis has the basal half of the forewing lightly tinged with yellow in contrast to the pure white basal forewing found in huita.

The dark, large patch of the distal half of the forewing of candefacta is dark and distinctly tinged with dark brown. In contrast this patch is completely olive-green in huita.
