Jeff Hahn, University of Minnesota
Size: 3/4 - 1 inch long (wingspan up to 2 inches long)
Where/When: Is associated with iris; can also be found at attracted to lights. Active August and September.
Significance: Larvae damage iris by tunneling through the leaves and eventually damaging the rhizomes which can kill iris plants. Feeding damage can allow the entry of a bacterial soft rot which can be very damaging to iris plants.
