forewing length = 17-21 mm (1)

Apamea cogitata is similar and narrowly overlaps the range of dubitans in the northeast, however cogitata is more reddish brown in the Northeast and can typically be separated from the more dark brownish black dubitans. (1)
Helotropha reniformis has a uniformly dark form that is very similar to Apamea dubitans. However, even the uniformly dark forms of H. reniformis exhibit some contrast in the ST/terminal area with the ST area being slightly paler than the darker gray terminal area. The ST/terminal area of A. dubitans is basically concolorous, showing very little contrast except for a series of dark chevrons that can be present along the inner side of the ST line.
