Which is a common sign of spider mite damage on plants?

A common sign of spider mite damage on plants is characterized by tiny yellow speckles on the leaves and the presence of webbing on foliage. These tiny yellow speckles, often referred to as stippling, occur as a result of the spider mites feeding on the cell contents of the leaves, which leads to chlorosis (yellowing) in the areas where they have fed. Additionally, spider mites produce fine silk webbing, which can cover leaf surfaces and create a noticeable visual indicator of their presence.

Recognizing these signs is crucial for early detection and effective management of spider mite infestations, as they can quickly lead to severe plant damage if not addressed promptly. The other signs mentioned, such as brown patches on the stem, wilting of leaves and flowers, or stunted growth, may be symptoms of various plant stress factors or other pests, but they are not specifically indicative of spider mite damage. Consequently, tiny yellow speckles along with webbing are the most direct symptoms linking to spider mite activity.
