Two-Spotted Spider Mite Infestation

Spider mites are common pests on Acer rufinerve, especially during hot, dry periods. They pierce plant cells to feed, leaving behind fine silken webs and causing stippling (small yellow dots) on the leaf surface.

Very Common

Southern Yellowhorn Mite (or similar Eriophyid mites)

Eriophyid mites are microscopic pests that can create fine, almost invisible webbing or felt-like patches on maple foliage. They often cause leaf distortions or galls in addition to web-like textures.

Common

Fall Webworm

While more common in certain regions, Fall webworms construct large, dense silk webs that envelop entire branches of maple trees. These webs protect the larvae as they consume the foliage.

Common

How to confirm: Check if the webbing is concentrated in large, thick clumps covering entire twig clusters rather than fine strands on individual leaves.

1 Manually remove the silk webs from the branches using gloved hands or pruning shears to disrupt the larvae's protection.
