Identification
A useful character for narrowing down an identification is the presence/absence of a strong W- shaped ‘wiggle’ in the subterminal line (ST line). This character is especially prominent in several members of the Hadeninae owlet moths (Noctuidae). I am using Robin’s #34610 to show this character and the inward-pointing black wedges that may be associated with the ST line.

Remarks
The classification used here follows The Moths of Canada CBIF site (linked to in the Internet References section below) which loosely follows Kitching and Rawlins, 1999, cited here.
The higher classification of the superfamily Noctuoidea is currently (2005) undergoing study and will no doubt change further in the near future.
