What symptom might indicate an infestation of spider mites on plants?

An infestation of spider mites on plants is often indicated by the presence of webbing, particularly on the undersides of leaves. This webbing is created by the mites as they feed and reproduce, serving as their protective habitat. The fine, silk-like threads can often be seen when you carefully inspect the leaves, especially if you look closely.

In addition to webbing, spider mites can cause a range of other symptoms, such as stippling or tiny yellow or white discolorations on the leaves due to their feeding activity. However, the characteristic webbing is a definitive sign of spider mite activity. Observing this webbing is crucial for diagnosing and confirming a spider mite problem, leading to appropriate interventions to manage the infestation.

Other symptoms may occur in conjunction with spider mite infestations, but the presence of webbing is specifically associated with these pests.
