Adult came to night light.

Amazing variability
It is hard to believe this is the same species as:



but the pattern of postmedian and antemedian lines is the same. Covell (1) says the coloration beyond the postmedian line is "variably heavy", but wow! A wonderful photo and specimen--thanks.

The old "double standard"
Yours has the colouring of a drab male; the other is the bright female.

 
Thanks, add info to guide?
Could you mention the dimorphism in the guide? This is not mentioned in Covell.

Excellent
Neat, and I put some thumbnails in where they seemed appropriate.
