Plants & places

Especially evergreen azaleas; some deciduous azaleas and mountain laurel.

Recognize the damage

Pale stippling develops into bronzed or bleached leaves; dark varnish-like waste appears underneath.

Before you act

Turn over several freshly stippled leaves and inspect with a hand lens, starting early in the season.

A sensible first response

Use a suitable site and reduce drought stress. Preserve predators and monitor early nymphs; any targeted treatment must reach leaf undersides.

When to look

Check from spring onward; multiple generations can accumulate through summer.

In Western North Carolina

A particularly useful diagnosis for azaleas in WNC landscapes, especially stressed plants in exposed sites.

Identification, lookalikes & further notes

Identification

Small adults have clear, lace-patterned wings; darker spiny nymphs cluster on leaf undersides.

Lookalikes & limits

Spider mites can also stipple leaves but lack lace wings; leaf scorch alone lacks the insects and dark waste.

In the garden

Pale stippling develops into bronzed or bleached leaves; dark varnish-like waste appears underneath.

What would help next

Record the host plant, date, fresh damage, and a clear photograph of the animal or insect. A damage match narrows the search; it does not establish an identification.
