Description

Adult Description: The adult Silver Leafhopper (Athysanus argentarius) is 7-8 mm in length with an ivory colored body. The body has straw colored lateral stripes on the dorsal side of the wings. There is also brown coloring on the legs and between the eyes.

Larva Description: Athysanus argentarius larvae are lightly colored and similar to the adult form with small brown markings on the legs.

Host Plant: Tall grasses including lawns and hayfields

Ecological Threat

Athysanus argentarius are a threat to tall grasses and are known to carry yellow aster disease, which currently has no cure.

Biology

The silver leafhopper is capable of migration to different areas due to its small size and flying ability. The leafhoppe takes fluids from the phloem of the host plant and can transmit the yellow aster disease which causes mass destruction to a field, even killing nearby trees.

History

Athysanus argentarius is native to the coastal regions of Europe. In the 20th century it migrated to North America and began expanding and establishing populations as far north as Montana and Michigan as well as coastal states such as Virginia.

Native Origin

Europe

Current Location

U.S. Habitat: Tall grasses and fields

U.S. Present: Athysanus argentarius is currently found in coastal areas of the United States.

Resembles

The Silver Leafhopper is similar to other leafhoppers in terms of shape such as the Red-streaked Leafhopper (Balclutha rubrostriata, but differs in total body color and lacks red stripes found on.

Management

Little information is available at this time regarding the Silver Leafhopper. Specific pesticides at this time are not known, but general insect pesticides that work on other leafhopper species are believed to be effective with the Silver Leafhopper as well.
