Latin Name: Erythroneura comes
Common Name: Grape leafhopper
Latin Family Name: Cicadellidae
Other Names: N/A
Pest Details
Origin:Apparently native to North America, and several species in the genus Erythroneura can be found throughout the U.S.
Biology:
The species of Erythroneura include the grape, three-banded, variegated, and potato leafhoppers, and these may feed on a wide variety of ornamental trees and shrubs in addition to their named host plants. When attacking crop plants such as grapes in large numbers the feeding causes premature leaf drop and poor quality to the fruit. Continuing annual infestations ultimately affect the overall health of the entire plant. Adult insects over-winter and emerge in the spring to deposit eggs within the tissue of the leaf. There may be 2 generations per year.
Identification:Adult insects are only about 3 mm long, with overwintering adults beginning reddish
Latin Name: Draeculacephala minerva
Common Name: Green Sharpshooter
Latin Family Name: Cicadellidae
Other Names: N/A
Pest Details
Origin:Native to North America, and occurring in the west from Texas to Oregon and south into Central America.
Biology:
This species is one of several leafhoppers that may vector a plant pathogen that causes Pierce’s Disease, a devastating disease in vineyards and other crops, as well as on many ornamental plants. The insect hibernates in the adult stage, in very early spring deposits eggs into the leaves of grasses, and may have three generations each year. It will feed on some broadleaf plants but strongly prefers grasses, including both cultivated and weed grasses.
Identification:Adult insects are about ¼ inch long, and a bright green color in spring and summer, tending toward brown in the fall and winter. Like other leafhoppers the wings are fully developed and held roof-like
Latin Name: Deltocephalus spp.
Common Name: Lawn leafhopper
Other Names: N/A
Pest Details
Origin:A number of native species occur in North America.
Biology:
This is a group of several related species that commonly infest lawns in large numbers. They may be hidden until someone walks across the lawn, triggering the adults to fly a short distance, but often almost in waves of numbers. The female inserts her ovipositor directly into the blades of the grasses to deposit eggs. Even though large numbers may be present in a lawn the visible damage to the turf is minimal to insignificant. The problem is often a nuisance problem as the adults fly and land on people who are active on the lawn. The adults also fly to lights and may be present around porch lights by the thousands, often entering a home when doors are opened.
Identification:Adult insects have fully developed wings that are held roof-like over the abdomen while at
Latin Name: Empoasca fabae
Common Name: Potato leafhopper
Other Names: N/A
Pest Details
Origin:The leafhopper is native to the eastern half of North America.
Biology:
Despite its common name this species feeds on over 200 different kinds of plants, including crops and ornamentals. The list includes row crops, annual bedding plants, fruit trees, and shrubs. Feeding is primarily on the underside of the leaf, and as the nymphs and adults feed they inject a toxin back into the plant that causes yellowing and stunted growth of the foliage. The discoloration begins at the leaf tip and margins and increases in size until the leaf finally dies. The insects spend the winter in warm areas along the Gulf Coast states, migrating north once the weather warms. Females insert their eggs into the plant tissues, several eggs per day for a month. There may be up to 4 generations per year in warmer climates.
Identification:The adult insect
Latin Name: Fieberiella florii
Common Name: Privet leafhopper
Other Names: Flor’s leafhopper, Cherry leafhopper
Pest Details
Origin:Native to Europe but well established throughout North America.
Biology:
This leafhopper is a pest on shrubs such as privet, photinia, and laurels as well as on members of the rose family (cherry, apple, apricot) and many other ornamental shrubs and trees. Eggs overwinter on the bark of trees and nymphs emerge in the spring.
Identification:Nymphs are greenish yellow with white mottled markings down the back of the head, thorax, and abdomen. Many long, stiff hairs protrude from the end of the abdomen. Adults are whitish with brown veins on the wings and a brown streak through the middle of the wing. The head is flattened. The wings are held roof-like over the abdomen and come together tightly at the end to have a strongly flattened profile.
Characteristicts Important to Control:
Latin Name: Corythucha pergandei
Common Name: Alder lace bug
Other Names: N/A
Pest Details
Origin:This is a native insect in North America.
Biology:
In cold regions the bugs will be dormant through the winter as either adults hidden under crevices in the bark or in piles of fallen leaves, or as eggs laid within the tissues of the leaves of evergreen trees. In the spring eggs hatch, the new nymphs undergo several stages over about a 6 week period, and the winged adults appear. Several generations can be expected each year. They feed by means of a proboscis that is inserted into the leaves and fluids are removed. Extensive feeding leads to chlorosis and a general mottled or stippled look to the leaves, along with heavy accumulations of dark fecal droplets.
Identification:The presence of lace bugs may be noted by the mottled look to the leaves, along with the insects and the characteristic black fecal spotting on the undersides
Latin Name: Pseudacysta perseae
Common Name: Avocado lace bug

Origin:This is a native insect in North America, possibly native to the Southeast U.S.

Extensive feeding leads to chlorosis and a general mottled or stippled look to the leaves, along with heavy accumulations of dark fecal droplets. This species is a pest of avocado trees in California, the southeast U.S., as well as the Caribbean, Mexico, and parts of South America. It
