In late spring, the adult moth will emerge from its pupa. They have black spikes on each side of their bodies, and two horn-like projections on the second thoracic segment. The greenstriped mapleworm has a bright red to black head and a yellow-green body with seven green stripes that run from the head to the abdomen. Consecutive defoliation events year after year can result in stunted growth and dieback. Each mapleworm is capable of consuming several leaves, resulting in major defoliation when infestations are large. They feed in early summer, from May to June in North Carolina. The greenstriped mapleworm ( Dryocampa rubicunda) is a defoliator of maples and sometimes oaks in close proximity to maples. Greenstriped Mapleworm Skip to Greenstriped Mapleworm More information about gloomy scale can be found from NC State Cooperative Extension. Chemical or biological control may be recommended for large infestations. Management strategies include cultural controls such as choosing proper planting sites and reducing tree stress. In large infestations, the scales give the tree a bumpy appearance due to the crowding of insects on the bark. Underneath this covering, the individual insect is pale pink and circular in shape. The cover is ~2mm wide and tends to blend in with the bark. These scale insects are armored, meaning they have a shield-like cover over them which can be separated from their bodies. The trees might also experience damage from scale saliva inserted during feeding. The insects use their piercing mouthparts to feed on storage cells under the tree bark, which can cause stunted growth, twig dieback, and thinning in large infestations. Specific epithet of rubrum meaning red is everywhere in evidence: red flowers in dense clusters in late March to early April (before the leaves appear), red fruit (initially reddish, two-winged samara), reddish stems and twigs, red buds, and, in the fall, excellent orange-red foliage color.Gloomy scale ( Melanaspis tenebricosa) is a pest of soft maples, especially red and silver maples, but it can also impact other maples, such as boxelder and sugar maple. Genus name is the Latin name for a maple tree. ![]() Flowers on a given tree are primarily male or female or monoecious and appear in late winter to early spring (March-April) before the leaves. Leaves are medium to dark green above and gray green below. Lobes have toothed margins and pointed tips. Leaves (to 2-5" long) have 3 principal triangular lobes (sometimes 5 lobes with the two lower lobes being largely suppressed). Quality of red fall color on species plants is variable. Emerging new growth leaves, leafstalks, twigs, flowers, fruit and fall color are red or tinged with red. In northern states, red maple usually occurs in wet bottomland, river flood plains and wet woods, but in Missouri it typically frequents drier, rocky upland areas. It grows faster than Norway and sugar maples, but slower than silver maple. It typically grows 40-60’ tall with a rounded to oval crown. Acer rubrum, commonly called red maple, is a medium-sized, deciduous tree that is native to Eastern North America from Quebec to Minnesota south to Florida and eastern Texas. ![]()
