Dogwood borers are clearwing moths whose larvae bore into dogwood trees and other ornamental plants. These insects are considered important pests of flowering dogwoods because larval tunneling weakens trees and may lead to branch dieback.
Quick Facts
- Scientific Name: Synanthedon scitula
- Family: Sesiidae
- Habitat: Forest edges, gardens, and ornamental landscapes
- Diet: Tree bark and inner wood tissue
- Status: Tree pest
Identification
Adult dogwood borers resemble small wasps due to their clear wings and slender bodies. The larvae are pale caterpillars that tunnel beneath the bark of host trees.
They belong to a group of borer insects that damage trees and shrubs.
Distribution
Dogwood borers occur across eastern North America where dogwood trees are common in forests and ornamental landscapes.
Life Cycle
Eggs are laid on tree bark, particularly near wounds or damaged areas. After hatching, larvae tunnel beneath the bark and feed on inner tissues before pupating.
Pest Status
Infested trees may show signs of decline, including cracked bark, sawdust-like frass, and weakened branches.
Prevention
- Avoid injuring tree bark
- Maintain healthy trees through proper watering
- Inspect trees regularly for signs of infestation
Control
Healthy tree care and early detection are the most effective strategies for managing dogwood borer infestations.
