What other evidence do lacebugs leave behind?

Lacebugs are known for their feeding habits, which primarily involve sucking sap from the leaves of host plants. As they feed, they not only impact the plant's health but also leave behind distinct markers of their presence. One of the most recognizable signs of lacebug activity is the presence of black spots of excrement on the leaves. These spots are small and dark, resulting from the droppings of the lacebugs, and they can often be found clustered on the undersides of leaves where lacebugs tend to reside. This excrement can indicate a significant infestation and is a useful diagnostic feature for gardeners and pest control professionals attempting to identify lacebug problems.

Other signs such as webs, holes in leaves, and rust-colored markings, while indicative of other types of pest activity or plant issues, are not directly associated with lacebug infestations. Thus, understanding that lacebugs primarily leave behind black spots of excrement is crucial for effective identification and management of these pests.
