Inverted Y Slug Moth - Apoda y-inversum

Inverted Y Slug Moth - Apoda y-inversum
Moccasin Lake, Winston, Douglas County, Georgia, USA
May 29, 2009
Size: 30mm span measured
Attracted to UV light. I kept studying all the Slug Moths in MPG and BG.N and was never completely satisfied with the patterns I was seeing. Upon reading Dennis Profant quotes about both A. y-inversum and Tortricidia flexuosa I was even more perplexed. Lastly I settled upon spreading the specimen and measuring it. It seems that T. flexuosa has a span of only 20mm while A. y-inversum is 25 - 30mm, mine clearly being in the latter group. If I am in error, please advise.

You Are Correct
This is the 3rd or 4th photo showing the median area filled like this. Mark Dreiling has one parked at the genus level that should be moved here. In his case the filled area is black rather than brown. The more typical moths can have either brown or black lines.
