Two-Spotted Spider Mite Infestation

Spider mites are the most common cause of fine webbing on melon plants, particularly in hot, dry conditions. They feed on the underside of leaves, extracting chlorophyll and leaving behind tiny white speckles and silken webs.

Very Common

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

Tetranychus urticae (European Red Mite) Outbreak

A specific subspecies of spider mite that thrives in melon greenhouses or warm outdoor summer climates. These mites create dense webs around new growth and fruit clusters to protect themselves from predators.

Very Common

High Humidity and Mite Proliferation

While humidity itself doesn't cause webbing, extreme fluctuations in moisture levels can trigger rapid lifecycle completions in mite populations. This leads to a sudden appearance of silk structures across the melon canopy.

Common

lightbulb

How to confirm: Monitor your local hygrometer; sustained high humidity accompanied by low airflow often precedes heavy infestations.
