Harry,

Just out of curiosity, I did a little research into Rhyacionia to try and
learn a little more about species distribution.  In some technical forestry
papers online, I found several papers describing damage done by two species
to loblolly pine plantations in the southeast:  R. rigidana and R.
frustrana.  The type locality of frustrana is Virginia (not sure where the
common name Nantucket pine tip moth came from).  I could find no mention of
any other Rhyacionia in the southeastern coastal plain except for subtropica
which occurs in Florida.  If somebody forced me to put a species name on
your moth, even though it's not a perfect match, I think there is a pretty
good chance it is frustrana ( and an appropriate name given your difficulty
with it!).
