Gypsy moth is an insect native to Europe and Asia that has been severely weakening trees across North America. Gypsy moth was introduced to North America in the late ’s near Boston and has spread over the past century.

Despite the successful use of insect predators, as well as fungal and viral controls, gypsy moth populations do.Gypsy moth occurs in many types of forest and urban landscape on mainland Europe. This pest occurs in the form of outbreaks causing damage in up to thousands of hectares.

In European forests, climate change is expected to affect the distribution of tree species because conditions under which species grow well will shift northwards and higher up. The gypsy moth, Lymantria dispar, is one of North America's most devastating invasive forest pests.

The species originally evolved in Europe and Asia and has existed there for thousands of years. In the late s, the European gypsy moth was accidentally introduced near Boston, MA by an amateur entomologist.
