Two-Spotted Spider Mite Infestation

These microscopic arachnids feed on the underside of broccoli leaves, injecting toxins that cause stippling and the characteristic fine silk webbing. In high temperatures and low humidity, their populations can explode, quickly defoliating young broccoli plants.

Very Common

How to confirm: Hold a white piece of paper underneath a leaf and tap it to see if tiny crawling specks fall off.

Tetranychus urticae (European Red Mite) Activity

A specific species of mite common in brassica crops that creates dense webbing around the developing broccoli heads and leaf axils. This interferes with the plant's ability to photosynthesize effectively.

Very Common

How to confirm: Inspect the undersides of older leaves for small reddish or yellowish dots indicating feeding sites.

Leafminer Larvae Silk Residue

While typically characterized by serpentine tunnels, some stages of leafminer activity can leave behind fine, structural silk traces as they move through the mesophyll tissue of the broccoli leaves.

Common

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