Stiria?

[Tom Middagh]

Looking in my drawer of moths to see what's what and I came across a Stiria 
that in my younger days I thought was intermixta but after doing a little 
searching on the net it looks like there is some choices.  Looks like the 
separation is by location so what I have is likely S. rugifrons.  I am 
wondering what physical things separate these two moths.  Or is it one of 
those DNA things.   I was wondering if you guys had any thoughts?
