Dave,   Made the change this time!
There are a few similar species of these noctuids.  My first guess, 
when I saw the photo and the reference to cotton nearby, was 
Heliothis virescens, which is called by different common names 
depending on what it feeds on: Cotton Bollworm, Tomato Fruitworm, or 
Tobacco Budworm.  At least that's how I learned it.  I've also seen 
them often on petunias in gardens both in Calif. and Oregon.  Tom has 
much more experience with noctuids than I do, so I'd go with him on 
this one.  But some of the ones you see in the traps may still be 

Cheers, Rich
