Four-lined Plant Bug


The injury caused by this insect is often confused with leaf spot diseases.

Eggs laid in early summer hatch out the following spring. The adults are present in for about six weeks during May and June.

The insects are not often seen but are bright yellow or green with black stripes.

The feeding of these insects causes reddish brown spots to form on the leaves. The youngest leaves are often the first to show the symptoms.

The insects rarely cause serious injury.

Malathion is labeled for this pest.
