Caterpillar Look-alikes to Spongy Moth

The spongy moth is just one of many insects that feed on tree leaves. There are several caterpillars common to Fairfax County which are often mistaken for spongy moth. Each of these has definite identifying characteristics which are true to the species. No two insect species have the same characteristics. The information provided here will aid you in differentiating the spongy moth caterpillar from others.

There are many insects that feed on trees. The correct identification of a problem insect is essential to controlling that specific insect properly. Fortunately, the control of most insects is rarely necessary since they seldom cause significant damage.

For more information, please contact the Fairfax County Forest Pest Branch at 703-324-1770, TTY 711, or by email.  You may also visit the Virginia Cooperative Extension for more information about pesticide safety and insect identification and control measures.
