Two-Spotted Spider Mites (Tetranychus urticae)

These microscopic arachnids thrive in warm, dry conditions and feed on the underside of Brassica leaves, injecting toxins that cause stippling and silk production. The fine webbing is a characteristic protective structure used by mite colonies to move across the plant.

Edible Mite/Small Spider Species

Non-pest spider species may build small, isolated webs on the foliage of ornamental cabbages while hunting smaller insects. Unlike spider mite infestations, this webbing usually lacks widespread leaf stippling or yellowing.

Thrips Infestation

While thrips are primarily known for silvery scarring on Brassica leaves, heavy infestations can sometimes be associated with secondary webbing or silk from other small insects attracted to the damaged plant tissue.

Common
