This species is a vector of false blossom virus of cranberry in the Eastern United States. It was first reported as a suspect vector of this virus by Dobroscky in 1928 (212) under the name of “Euscelis striatulus Fallen.” Later in 1929 and 1931 Dobroscky (213, 214) confirmed transmission of the virus after feeding leafhoppers on diseased plants for certain periods of time, and then he transferred infective’ insects to healthy cranberry plants, where they fed for 2 weeks. Experimental work carried out for a period of 4 years gave positive results of transmission. In one experiment the incubation period was determined as 21 days in the vector. Experiments on natural transmission proved negative.
This species is an important vector of this virus in the Eastern United States.
Small, slightly robust species. male 3.50—3.70 mm., female 4.00—4.50 mm.
General color light brown to dark brown. Crown light brown with dark transverse lines; pronotum light brown with black markings; elytra brown to almost black, veins light brown; male more deeply marked than females.
Pygofer in lateral aspect about twice as long as wide, caudal margin with small lobe on caudoventral margin; aedeagus in lateral aspect broad basally, narrowed at apical half, curved laterally, shaft with lateral hooked subapical processes in ventral aspect; gonopore apical; style in dorsal aspect with short, narrow apices; female seventh sternum in ventral aspect with caudal margin excavated on each side of middle.
