Mint-Ligurian Leafhopper

Ligurian leafhopper (Eupteryx decemnotata)

Pest description and crop damage Adults are tiny, less than 0.12 inches, yellowish-green with a characteristic pattern of spots on the head and the wings. The Ligurian leafhopper is an important pest in cultivations of plants in the family Lamiaceae (mint). Just like other leafhoppers, they are sap-feeding insects causing damage by puncturing cells and removing the contents. The characteristic stippling is produced when pest density is high. The damage can be mistaken for thrips or mite injury.

Biology and Life History This is a new species first detected in Oregon in 2020. Leafhoppers typically lay their eggs in stems, leaf tissues and petioles of plants, so they are nearly impossible to detect. After eggs hatch leafhoppers will pass through five nymphal instars over the course of 20 days before reaching adult stage. Like adults, nymphs can hop.

Management Since pest status is unknown, no information exists.
