The Causes of Webbing on Leaves

There are several reasons why your plant may be developing webbing on its leaves. Some of the most common causes include:

Spider mites: These tiny, eight-legged pests are a common culprit behind webbing on leaves. Spider mites feed on plant sap, causing damage to the leaves and stems. As they feed, they spin webs to protect themselves from predators and to create a habitat.

Mealybugs: Mealybugs are small, white insects that feed on plant sap, causing damage to the leaves and stems. They can also spin webs to protect themselves from predators.

Aphids: Aphids are small, soft-bodied insects that feed on plant sap, causing damage to the leaves and stems. They can also produce a sticky substance called honeydew, which can attract ants and other pests.
