Spider Mite Infestation

Spider mites are the most common cause of fine, silken webbing on maple leaves, particularly during hot, dry periods. They feed on the sap of the Acer cappadocicum, causing stippling and eventual leaf drop.

Fall Webworm

The larvae of Fall webworms create dense, silken webs that envelop entire clusters of leaves on maple species. While more common in late summer, these webs can cause significant defoliation if left untreated.

Clothoota (Leaf Miner) Secondary Effect

While leaf miners create trails inside the leaf, a heavy infestation can weaken the leaf tissue, making it more susceptible to secondary opportunistic mites that spin fine webbing.

Common

How to confirm: Look for serpentine, light-colored tracks on the surface of the maple leaves underneath the webbing.
