Use the photos below to distinguish
between grape leafhopper and variegated leafhoppers, and to identify leafhopper
damage. Parasitism may result in economic control of grape leafhopper
but is less likely if the variegated leafhopper is the key species. Names
link to more information on identification and management.
Also look for evidence of egg parasitization by viewing photos
of leafhopper predators and natural enemies.

| Variegated leafhopper |
Grape leafhopper |
Variegated leafhopper (first-instar
nymph)
Identification tip: Nymphs are almost transparent when they
first emerge, except for a very slight yellowish coloration.
|
No photo available.
The first-instar grape leafhopper
is almost colorless, except for prominent red eyes.
|
Variegated leafhopper (third-instar
nymph)
Identification tip: When a nymph matures it becomes orange
brown to yellow brown, in contrast to the nymph of the grape leafhopper
which remains whitish.
|
Grape leafhopper (fifth-instar
nymph)
Identification tip: Nymphs of the grape leafhopper are white
with pale-yellow markings.
|
Variegated leafhopper (adult)
Identification tip: The adult is darker than the grape leafhopper
adult and mottled brown, green, and white with a reddish tinge. It
has white patches on the lower middle margin.
|
Grape leafhopper (adult)
Identification tip: The adult grape leafhopper is light to
pale yellow with more well-defined markings than the variegated
leafhopper adult. |
| Leafhopper damage |
|---|
Leafhoppers cause stippling or light-green spotting from feeding on
leaf surface.
|
Heavier leafhopper feeding damage causes more intense stippling. Black
sooty mold is growing on the leafhopper excrement (honeydew) on
this leaf.
