What Do Spongy Moths Look Like?
Lymantria dispar is the scientific name for the spongy moth. The adults are not as damaging as the spongy moth caterpillar. These larval pests feed on the foliage of more than 300 tree species. The adults are different in appearance based on sex. Females are 1.5 inches (3.8 cm) long, creamy white, with a V marking on the back wings. They also do not fly. Males are mottled brown and gray, and are active in the afternoon and evening as they search for a mate. They also have pronounced feather-like antennae. The caterpillars have pairs of red and blue spots on the back topped with black hairs. Spongy moth eggs are beige and soft, almost fuzzy masses. In the pupa stage, the casing is deeply maroon and hard.
Spongy Moth Life Cycle
Like other moths, spongy moths have 4 development stages: egg, larva, pupa, and adult. The egg casings appear in August and will overwinter. Around mid-May, the larva chews its way out of the casing and begins to feed. Once the larva is fully grown, about 2.5 inches ( 5.35 cm.) it will shed its skin, and the new skin hardens and deepens in color. Within a week or 2, the casing splits to reveal the adult moth.
How to Identify Spongy Moth Damage
While spongy moth larvae will feed on many species of trees, they do have preferred food. Spruce, Douglas fir, white birch, witch hazel, pine, linden, apple, oak, willow, crabapple, mountain ash, and basswood are some favorites. They also like many species of hardwood trees. Their feeding damages tree health by defoliating the plant. They are voracious in this stage and can completely remove all the leaves. This is damaging to tree health because trees need leaves to photosynthesize. They turn solar energy into tree sugars that they use as a source of energy. In deciduous trees, the moths’ feeding begins on the edges and produces a ragged appearance. In evergreen, needled plants, the needles will be eaten off the plant.
Spongy Moth Prevention
If possible, remove the egg casings. From mid-October through April these will be found on tree bark, signs, buildings, fences, and other outside surfaces. If the mass is on a tree, do not try to scrape it off as this will damage the bark. Use horticultural oil labeled for use against spongy moths. Removing even 1 egg mass could reduce the next year’s population by around 600. If the egg casing is in an area that can safely be scraped off, soak the eggs in soapy water for 2 days to kill the developing insects.
How to Get Rid of Spongy Moths
Encouraging natural enemies by avoiding the use of broad spectrum pesticides is the first defense. Young caterpillars can be killed by spraying Bacillus thuringiensis. There are several sprays on the market listed for use against spongy moths. There is also an injectable product that goes directly into the trunk base of the tree. If you choose to manually remove adult moths and larvae, wear gloves since contact can cause an allergic reaction.
