Japanese beetle
Popillia japonica

One of the most recognizable causes of lacy, skeletonized leaves in summer.
Roses, grapes, many trees, shrubs, and other ornamentals; larvae feed belowground.
Recognize the damage
Adults remove leaf tissue between veins and can chew flowers or fruit.
Before you act
Look for actively feeding adults on fresh damage. Examine the plant as well as the beetle; lawn grubs require a separate inspection.
A sensible first response
Hand-collect manageable numbers into soapy water. Monitor new foliage and protect valued plants; treating lawn grubs does not prevent beetles arriving from elsewhere.
When to look
Adults mainly in summer; emergence shifts with elevation and weather.

Identification, lookalikes & further notes
Identification
Metallic green adults have coppery wing covers and distinct white hair tufts along the abdomen.
Lookalikes & limits
Green June beetles are larger; several other metallic leaf beetles lack the same white tufts.
In the garden
Adults remove leaf tissue between veins and can chew flowers or fruit.
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.
LOOK CLOSELY
Compare the clues.
Compare the animal or insect, its life stage, and signs of activity. Similar damage can have different causes. Images are not at the same scale; species references may show different cultivars.
