See Also
Airy Apamea (A. vultuosa) has no ST line - just a color contrast between terminal and subterminal areas; Common Apamea (A. vulgaris) has similar markings but a uniformly dull brown forewing (compare images of all three species)
Confused Woodgrain (Morrisonia confusa) is also similar but has two black basal dashes and several dark streaks on forewing (see pinned image); it also flies earlier [April, May] than Wood-colored Apamea
