Two-Spotted Spider Mite Infestation

Spider mites thrive in hot, dry conditions and create fine silk webbing to protect themselves and their eggs on the undersides of cabbage leaves. They feed by piercing cell walls, which leads to stippling (small yellow dots) and eventual leaf chlorosis.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it to see if tiny moving specks fall onto the paper.

Agromyzid Fly Larvae (Leaf Miners) Secondary Webbing

While primary symptoms are serpentine tunnels, heavy infestations can cause localized plant stress and secondary silk production by other small pests attracted to the decaying tissue.

Common

How to confirm: Look for winding, translucent 'trails' or tunnels inside the leaf tissue near the webbing.

Thrips Infestation

Thrips can cause fine silken webbings in high-density populations as they congregate in leaf folds, often accompanied by silvery scarring on the cabbage leaves.

Common

How to confirm: Check for tiny black specks (excrement) and silvered, dried patches on the leaf surface.
