Lawn and Turf : Leafhoppers
(revision date: 3/12/2014)


Biology
Leafhoppers are slender, somewhat wedge-shaped insects that hop or fly just above the lawn surface when disturbed. They are variously-colored, from yellowish to green to gray-brown. The wings are typically held roof-like above the body, which is 1/4" or less in length. Nymphs (immature leafhoppers) are similar to adults but lack wings. Nymphs and adults feed on grass leaves and stems, causing blades to appear mottled or streaked with white. Damaged areas in lawns appear bleached or dried.
Management Options

Non-Chemical Management
  • Several insects feed on leafhoppers including damsel bugs, assassin bugs, and parasitic wasps. When possible, avoid use of broad-spectrum insecticides which kill beneficial insects.
Select non-chemical management options as your first choice!
