Two-Spotted Spider Mite Infestation

The presence of fine webbing on the foliage of Zantedeschia is a classic sign of spider mites, which thrive in warm, dry conditions. These tiny arachnids pierce plant cells to suck out nutrients, leading to stippling and eventual leaf senescence.

Very Common

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

Tetranychus urticae (European Red Spider Mite) Outbreak

In many indoor or greenhouse environments, specific strains of red spider mites create dense silken webs around the base of the spathe and leaves to protect their eggs. This often occurs when the humidity levels surrounding the Calla Lily drop too low.

Very Common

How to confirm: Inspect the undersides of the leaves for minute orange or reddish dots that move slowly.

warning

Low Humidity and Environmental Stress

While not a direct cause of webbing, extremely dry air can weaken the Zantedeschia's cuticle, making it easier for opportunistic pests to establish webs. This stress often manifests as fine, desiccated strands along leaf edges before full infestation occurs.

How to confirm: Use a hygrometer to check if your environment is consistently below 40% humidity.
