Black-ledged sharpshooter

Basionym: Aulacizes noveboracensis Fitch, 1851
Published in: Fitch, A. (1851a) Catalogue with references and descriptions of the insects collected and arranged for the State Cabinet of Natural History. Annual Report of the Regents of the University on the Condition of the State Cabinet of Natural History, and the Historical and Antiquarian Collection 4, 43–69.

Description & Identification

Large, slightly robust species. male 7.20—7.40 mm., female 7.50—8.50 mm. (Nielson, 1968)General colour green. Crown green with dark spot on either side of apex and spots on anterior margin next to eye; pronotum and scutellum light green; elytra sometimes dark green, weakly reticulated apically, veins light green.(Nielson, 1968)Pygofer in lateral aspect about 214 times as long as wide, dorsal margin distinctly concave, caudal margin broadly convex; aedeagus in lateral aspect somewhat recurved, broad medially with pair of broad lateral processes, shaft constricted subapically in ventral aspect; paraphyses symmetrical with two pairs of processes, terminal pair curved and nearly twice as long as basal pair; style in dorsal aspect with apical half sharply attenuated; female seventh sternum in ventral aspect with distinct spatulate process on middle of caudalmargin. (Nielson, 1968)This species is related to crassicornis in general habitus and can be distinguished by the aedeagus with shaft constricted subapically and slightly expanded laterally at apex in ventral aspect.(Nielson 1968)

Biology & Ecology

The biology is unknown. In 1956, Beirne (58) recorded it from moist habitats, but did not list host plants. It was found feeding mainly on grasses in low areas in Washington by Wolfe in 1955 (866). (Nielson, 1968)

Worldwide Distribution

United States,Canada (Young 1977a).It is widely distributed in the United States and Canada. Beirne in 1956 (58) reported it from the Provinces of British Columbia, Yukon, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, and Nova Scotia. Young and Davidson (882) recorded it from Maine, Vermont, New Hampshire, New York, Pennsylvania, Minnesota, Illinois, Wisconsin, Iowa, North Dakota, South Dakota, Nebraska, Colorado, Utah, Montana, Idaho,California, Washington, and Oregon. Apparently it does not occur in the Southern or Southwestern United States. (Nielson, 1968)

Vector Status

Economic Crops


This species is a vector of Pierce’s disease virus of grape in California. In 1952, Freitag et al. (287) were first to report this species as a vector of this virus. Leafhoppers fed on diseased plants from 1 to 2 days and on test plants from 2 to 10 days. It was not an efficient vector, having infected only 20 percent of the test plants. Studies on natural infectivity of the vector by Freitag and Frazier in 1954 (286) showed that over 1,100 test specimens failed to transmit the virus.(Nielson 1968)This species is not considered an important vector of this virus.(Nielson 1968)
