Moved from Petrophila cronialis. The original supposition that this is P. avernalis is correct. Characteristics include the zigzag medial white line as it nears the costa, the kink in the first subapical white ray near the costa, and the dark patches in the PM area between these two white lines. The range is correct for avernalis.

This moth does not match either Druce's original (1896) description of P. cronialis* nor Munroe's (1972) redescription in his monograph on the subfamily (1). Those refs both describe the forewing as strongly and evenly suffused with brownish gray with only a weakly-defined pale median line "almost straght, but slightly concave distad". This moth also looks quite different from the single specimen illustrated on the BOLD page for the species.

I don't know the SW Petrophila's very well but I might suggest that this could be P. avernalis or P. hodgesi.
