It is my understanding that the iris borer is indigenous only to the eastern
U.S., no place else. It was here long before the Europeans came. And what
did it eat...why I. versicolor, I. virginica, I. hexagona, I. fulva, I.
setosa, etc, i.e. irises indigenous to the eastern U.S. Interestingly, if
borer gets into I. versicolor it does not seem to do as much damage to a
clump as it will in a bearded iris. Dispite the exhange of irises between the
West Coast and East Coast, and the East Coast and Europe....the borer has
never gotten established any place beyond its native habitat. Its irises of
preference are in the the East U.S....and there is where the borer is likely
to remain...Everyone not in the east ern U.S. be grateful! Clarence Mahan in
