Gypsy moth, Lymantria dispar dispar (Linnaeus) (Lepidoptera: Erebidae), is an exotic invasive species introduced from Europe that is spreading south and west in North America. In spring and early summer, gypsy moth caterpillars feed on the leaves of many different tree species, especially oaks. During outbreaks, caterpillars defoliate entire forests.
