Empoasca leafhoppers

Empoasca fabae

Several species of leafhoppers are found in dry beans with Empoasca fabae and E.solana being the most common. They are nearly identical morphologically and can only be distinguished by experts. The damage they cause is also nearly identical as are the treatment guidelines.
Empoasca leafhoppers are small (0.125 inch [3 mm] long), bright green, wedge-shaped insects. The small, wingless nymphs (immatures) are also wedge shaped and green and move rapidly forward, backward, and from side to side. Both adults and immatures are found primarily on the underside of leaves.
