Two-Spotted Spider Mite Infestation

The presence of fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often found with Anthurium Otazu. These arachnids pierce plant cells to feed on sap, leading to stippling and eventual leaf drop.

Very Common

Broad Mites

While Broad Mites are too small to see with the naked eye, they can cause structural distortions and fine silken appearances on new growth. In Anthuriums, this often manifests as stunted, distorted leaves that appear somewhat 'webby' or scarred.

Common

How to confirm: Inspect the newest, most tender growth for puckering, curling, or bronze-colored discoloration.

Low Humidity leading to Secondary Pest Attraction

Anthurium Otazu requires high humidity; when levels drop below 50%, the plant's physiological stress makes it more susceptible to mite attacks. The webbing itself is a response to the pest, but the root cause is often an arid microclimate.

How to confirm: Use a hygrometer to check if your ambient humidity stays consistently above 60% for this species.

1 Increase local humidity levels to above 50% by using a humidifier or a pebble tray to create a more tropical microclimate.
