![]() The greenstriped mapleworm has several natural enemies but none have been recorded in great abundance. Since the caterpillars feed in groups, often a single branch is infested that can be pruned. If clusters of yellow eggs are found, scrape them off or remove the entire leaf to reduce the caterpillar population. However, excessive fertilizer may increase pest abundance by making trees more nutritious to pests and reducing the trees’ natural defenses. Reducing plant stress by proper planting and watering may reduce susceptibility to pest infestations. Intervention Skip to Intervention Cultural Control This type of defoliation can seriously weaken maples to the point that borers and fungi may infest the trees and finish them off. Older literature refers to episodes in which the first generation strips maples bare, and then just as a new flush of growth emerges, the second generation emerges to defoliate the trees again. Rarely will the tree suffer long term damage but loss in growth and branch dieback may occur if the same tree is defoliated several consecutive years. Large populations of mapleworms can defoliate trees if unnoticed or without proper management. Larvae are the only herbivorous life stage, capable of devouring several entire leaves per caterpillar. Adult moths can have a wingspan of 37 to 50 mm. Full-grown larvae can reach 40 mm in length. There are two prominent horns on the second thoracic segment, two rows of short spines on the side of the body, and four larger spines on the terminal abdominal segments. ![]() The larvae have red or black heads, pale-green bodies with seven dark-green longitudinal stripes. The moths deposit yellow eggs on the underside of leaves. The body of the moth is yellow on top and pink on the bottom with wings exhibiting yellow and pink colorations that vary in design. They are commonly known as the rosy maple moth. In North Carolina, moths emerge from their pupae in late April or early May. Some oaks can also be damaged especially when in close proximity to maples. Maples are its preferred hosts and the most common hosts in many landscapes. The greenstriped mapleworm, Dryocampa rubicunda, is found throughout the Eastern United States and Canada.

Once the caterpillars turn into moths, they won't damage your maple tree at all like all moths in the family Saturniidae, the adults do not eat! #BenInNatureĪbout this post: Social distancing can be difficult, but the next few weeks present a great opportunity to become reacquainted with nature. ![]() While they can cause aesthetic damage, they won't kill your maple tree. As the common name suggests, the caterpillars of these moths prefer to feed on the leaves of maple trees. The rosy maple moth definitely isn't a giant, but its fuzzy pastel coloration makes it a striking sight nonetheless. This moth belongs to the family Saturniidae - the great silk moths - which includes some of the largest moths in the world. Case in point: Dryocampa rubicunda, also known as the rosy maple moth. Sure, a lot of moths are kind of drab, but there are plenty of beautiful moths out there, too. Everyone loves butterflies, but moths often don't get the respect they deserve.
