The Ohio Department of Agriculture (ODA) announced this past week that Box Tree Moth (BTM) (Cydalima perspectalis, family Crambidae) had been confirmed in Hamilton and Clermont counties in southwest Ohio. The location is near where the two counties meet Warren and Butler counties. It’s the first time this non-native boxwood (Buxus spp.) defoliator has been found in Ohio.
Boxwoods are some of the most common plants in Ohio landscapes and remain a mainstay of our nursery industry. BTM caterpillars defoliate boxwoods and will strip bark once they run out of leaves to eat.
