Spider Mites (Tetranychidae)

Tiny arachnids feed on the sap of the Tatarian maple leaves, leaving behind fine silken webs as they move and reproduce. This often manifests during hot, dry periods when the tree is under moisture stress.

Very Common

Spotted Tent Caterpillar

The larvae of these caterpillars construct silk webs (tents) on branches or within foliage to protect themselves while feeding. While more concentrated than mite webbing, early stages can appear as fine silken structures among the leaves.

Common

How to confirm: Look for larger, more dense silk clusters and search for small green caterpillars moving near the webbing.

Fall Webworm

These larvae create large, conspicuous web nests in the canopy of maple species to feed on the foliage. The webbing is much more structural and dense than mite silk, often enclosing entire branch tips.

Common

How to confirm: Inspect larger, thicker web masses that appear specifically on the outer edges of the leaf clusters during late summer.
