Comment: Empoasca is a very large genus, with many, many species occurring in not only North America but also the eastern United States. The genus is currently undergoing taxonomic revision, which should hopefully make identifications a bit easier in the future. For the time being, it is very likely that outside of a small number of species, identification to species level will not be possible without at least a view of the male subgenital plates or female pregenital sternite, and more likely dissection of a male. E. fabae is one exception, as a clear image showing the characteristic 6 pale spots along the anterior margin should allow for an identification to species level; most other Empoasca listed below either have 3 spots or lack spots altogether. E. coccinea is another exception, as it tends to have a somewhat distinctive color pattern. This page exists as an umbrella for any Empoasca photographed in the state that cannot reliably be identified to species level. Below are the description of greenish Empoasca that have been recorded in the state; information came from: 3I, (DeLong, 1931)

bifurcata- A bright green species with a golden-yellow head that is mottled with paler yellow around the ocelli. The pronotum is greenish with golden-yellow coloration; there are three large white spots on the anterior margin, one in the middle and one behind each eye. The scutellum has a broad central white longitudinal band. The face is pale, without any dark spots. The wings lack any spots and are a bright green color; the apices are not colored and the venation is green. The male subgenital plates are long, slender and pointed; they are slightly divergent from one another and curve backwards near the apices, unique for and characteristic of this species. The female pregenital sternite is rectangular, being wider than it is long; there is a very slight median projection. Adults are 3.2-3.5 mm long. For images of this species, see: BG.

The pronotum lacks any dark markings. The head is roundedly produced and bulbous, without any noticeable projection. The wings lack any dark markings and were greenish or smoky sybhyaline. The legs are green. The male subgenital plates are broad at the base but taper to pointed acute apices; they are slender. The female pregenital sternite has the posterior margin broadly and roundedly produced; it is more than twice as long as the previous segment. Adults are around 3.0-3.2 mm long. See: 1.

The scutellum has the lateral triangles typically outlined with white, with multiple pale lines instead of a single central pale band. The head is broadly rounded, only slightly pointed. The wings are greenish subhyaline. The male subgenital plates are long and slender, curving outwards near the tips and tapering to acute apices; they are divergent from one another. The female pregenital sternite is moderately produced and roundedly truncated; it appears largely rectangular. Adults are around 3.5 mm long. See: 1.

The male subgenital plates are long, slender and narrow, strongly diverging from one another. The female pregenital sternite is rectangular, with a largely straight posterior margin.

recurvata- The dorsum is a green color; there are few symmetrical cream-colored markings on the head and thorax. The face is pale, without any dark spots. The pronotum lacks any dark markings and has three white spots, which may sometimes be fused, along the anterior margin. The vertex is strongly rounded and bulbous; it has a pair of pale green spots near the margin. The wings lack any spots and are yellowish-green. The male subgenital plates are long and slender with acute, upturned apices. This species resembles E. bifurcata in general appearance. Adults are around 2.75 mm long.
