Macropsis osborni is a small, native, typical leafhopper. It occurs in the eastern United States and southern Canada. There are very few records and sightings of this species anywhere. They are all from Ohio, Wisconsin, Illinois, Missouri, Mississippi, Arkansas, and Oklahoma in the U.S., and Quebec, Ontario, and Manitoba in Canada. All of the sightings in North America have been from early June to mid-July except one, which was in April. There are five records or sightings from Minnesota since 1929, all in the Metro region.

Macropsis osborni feeds on plant juices of plains cottonwood and eastern cottonwood.

The female is yellowish-green and ¼″ (6 mm) in length. The body is robust.

The top of the head (crown) is short, and it projects forward between the eyes in a broad angle to a blunt point. The rear margin is broadly concave. When viewed from the side, the face appears swollen.

The plate on the first segment of the thorax (pronotum) is distinctly angled in front. The surface is densely and conspicuously grooved (striate). The striations are irregular and wrinkle-like. They radiate at an oblique angle from the center line toward the rear corners of the pronotum.

The plate between the wing bases (scutellum) is large, triangular, and green. The basal corners are tinted orangish-yellow. On each side of the thorax, the plate at the rear (epimeron) does not have a black spot.

The forewings (hemelytra) are longer than the abdomen. They are green and translucent, with a coppery tint. There is a broad, brown or black band across the base bordering the scutellum. Sometimes there is a dark patch at the wingtip.

The male is dark brown and 3⁄16″ (5 mm) in length. The basal corners of the scutellum each have a large, triangular, dark brown spot. Each epimeron has a single dark spot.

Male total length: 3⁄16″ (5 mm)

Female total length: ¼″ (6 mm)
