In this Guideline:
DESCRIPTION OF THE PESTS
Adults are 0.12 to 0.25 inch long, wedge-shaped, active insects that jump and fly short distances when disturbed. Colors vary by species and are often mottled or speckled with whitish green, yellow, and brownish gray. Adults insert eggs into turfgrass leaves. Nymphs lack wings; their color varies with species. Disturbed nymphs have a characteristic habit of moving sideways or backwards. Generation time varies from 12 to 30 days, depending on species and temperature.
All grasses can be affected by leafhopper feeding.
Although leafhopper sightings are not uncommon on golf courses and lawns, severe injury usually occurs only with large leafhopper populations. Both nymphs and adults suck sap from the leaves, resulting in yellowing or bleaching. Affected turfgrass lose vigor and may die as a result of extended presence of high populations.
Generally treatment for leafhoppers is not needed. Treat only if populations are high enough that damage is intolerable.
