Identification

Penthimia americana is an rare and unusual leafhopper. It occurs in North America east of the Great Plains. It is rare throughout its range, including in Minnesota. It is unusual because it resembles a spittlebug, looking nothing like other leafhoppers.

Adults are short, 3 16 to ¼ (5 to 6 mm) long. The body is smooth, shiny, and oval when viewed from above, convex when viewed from the side. The overall color varies from reddish-brown to black with numerous, small, white or pale spots.

The head is short and very broad, almost as wide as the exoskeletal plate covering the thorax (pronotum). The back of the head (vertex) is very broadly rounded.

The pronotum is widest at the base, narrower toward the head. The rear margin is broadly concave. The surface has distinct horizontal grooves. The plate between the wing bases (scutellum) is large and triangular.

The forewings (hemelytra) are thickened, leathery, very broad, and short, though long enough to completely cover the abdomen. They are widest in the middle and broadly rounded to a blunt point at the tip. There is an extension (selvage) at each wingtip which overlaps the adjacent wing. The selvage is broadly rounded. The hindwings are thin, membranous, a little shorter than the hemelytra, and concealed beneath the hemelytra.

The fourth segment (tibia) of the hind leg has a row of spines. The last part of the leg (tarsus), corresponding to a foot, has three segments.

Glossary

Hemelytron

The forewing of true bugs (Order Hemiptera), thickened at the base and membranous at the tip. Plural: hemelytra.

 

Pronotum

The saddle-shaped, exoskeletal plate on the upper side of the first segment of the thorax of an insect.

 

Scutellum

The exoskeletal plate covering the rearward (posterior) part of the middle segment of the thorax in some insects. In Coleoptera, Hemiptera, and Homoptera, the dorsal, often triangular plate behind the pronotum and between the bases of the front wings. In Diptera, the exoskeletal plate between the abdomen and the thorax.

 

Tarsus

The last two to five subdivisions of an insect’s leg, attached to the tibia; the foot. Plural: tarsi.

 

Tibia

The fourth segment of an insect leg, after the femur and before the tarsus (foot). The fifth segment of a spider leg or palp.

 

Vertex

The upper surface of an insect’s head.
