Right or wrong, I go by the info on BugGuide which may be the same as what
Covell suggests. As you say, it doesn't always work because I'll sometimes find
some that fit somewhere in the middle.
"Caenurgina erechtea.
Adult: two dark bands on each forewing do not touch each other near the
midline, and the inner (or more basal) band does not touch the inner
margin [whereas in C. crassiuscula, the bands almost touch each other near the
midline, and the inner (or more basal) band touches the inner margin]"

Hi All,
I find Caernurgina erechtea and C crassiuscula quite difficult to separate. I
think the marks suggested in Covell work for only some specimens--there are
just too many where they don't work. For a given generation erechtea is larger,
but the second generation of erechtea is the same size or smaller than the
first of crassiuscula. I think the 8th abdominal sternite can also be used, but
this requires a male specimen and the scales have to be brushed off.
I would love to hear from anybody who has a way to separate the males of these
two species. (Female erechtea are easy to ID because they are mostly unmarked.)
Don Lafontaine once told me that erechtea is actually relatively rare from the
northeast, and that it is mostly misidentified in collections. In this region
erechtea is a species of barrens and dune backs, whereas crassiuscula is found
in grasslands. I would suspect that this pattern holds in TN--i.e., that you
would be most likely to find it in sandy areas and open pine barrens with
grasslands.
