This species is a vector of elm phloem necrosis in the United States. Transmission of this virus was first reported by Baker in 1948 (15). A year later in 1949, he (16) confirmed results by duplicating previous tests. The leafhoppers were confined to diseased trees from 5 to 13 days and then transferred to healthy elms for 20 days. Five percent of the test trees were infected. In another experiment the insects transmitted the virus to 34 percent of the seedling trees after feeding on diseased sources for 20 days and test trees for 30 days. The incubation period of the virus in the insect’s body was not exactly determined, but evidently it was between 5 and 33 days.
(Nielson 1968)

This species is considered an important vector in the spread of this virus in elm in the United States.

Species Description

Length:
Medium size, slender species. Length of male 4.50—4.70 mm., female 4.80—5.20 mm.
.

Colour:
General color golden brown. Crown brown with dark line on anterior margin; pronotum brown; elytra brown with few scattered, irregular ivory spots.
.

Genitalia:
Pygofer in lateral aspect about 11/2 times as long as wide, caudoventral margin produced posteriorly to broad, obliquely truncate lobe; aedeagus in lateral aspect extremely short, shaft constricted medially, broad circular band basally; apex compressed caudally to form thin ridge; gonopore terminal; paraphyses symmetrical, apex foot shaped; style in dorsal aspect with apices elongate; female seventh sternum in ventral aspect with lateral margins narrowed, caudal margin notched at middle.

Species Diagnosis

From titanus, to which it is similar in genital characteristics, luteolus can be distinguished by the caudal margin of the pygofer which is somewhat pointed caudoventrally, the style which is truncate apically, and the aedeagus which has a ventral process projecting apically in lateral aspect.
