Two-Spotted Spider Mite Infestation

Spider mites are the most common cause of fine silk webbing on cowpea leaves. They feed on the underside of the foliage, causing stippling (tiny white dots) and eventually producing visible webs as the population grows.

Very Common

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

Leaf Miner Damage (Secondary Webbing)

While leaf miners primarily create serpentine tunnels, the physical degradation of the leaf tissue can sometimes lead to secondary fungal growth or localized silk-like structures from opportunistic pests.

Common

How to confirm: Look for winding, translucent trails inside the leaf blade rather than just surface webbing.
