Lymantria dispar, formerly gypsy moth, caterpillars feed on the leaves of oaks, aspen, crabapple and many other types of trees. Outbreaks of
Lymantria dispar are not frequent but when they occur, it can be unpleasant to live, work or recreate in an affected area.
Lymantria dispar caterpillars can be so abundant that many trees will be completely defoliated by early July. Several areas in Michigan experienced
Lymantria dispar outbreaks during 2019, and populations may be high in some areas again during summer 2020. Please
