These arachnids thrive in warm, dry conditions common during the growing season of Autumn Queen cabbage. They pierce plant cells to suck out nutrients, leaving behind fine silk webbing and stippled white spots on the leaves.

Very Common

Southern Yellow-Stained Webworm

The larvae of this moth species spin silken webs around cabbage leaves while feeding on the foliage. As they grow, the webbing becomes more dense and can eventually cover entire clusters of leaves.

How to confirm: Gently pull the webbing apart to look for small, caterpillar-like larvae hiding inside.

High Humidity/Fungal Mycelium

In extremely humid environments, certain fungal pathogens can produce a fine, thread-like appearance that mimics webbing. This is often accompanied by localized softening of the cabbage leaf tissue.

Common

How to confirm: Check if the 'webbing' is actually part of the leaf surface or if it can be wiped away easily with a damp cloth.
