Spongy Moth

×On March 2, 2022, the Entomological Society of America officially changed the common name of Lymantria dispar (previously known as the gypsy moth) to spongy moth.

The spongy moth (Lymantria dispar) is an important defoliator of trees. Originally from Europe, it was introduced in the late 1800s. Spongy moth caterpillars feed on hundreds of tree species but tend to prefer oaks, especially white and chestnut oak on ridgetops.
