Identification

This may be the most common large bush katydid. Adult males are 17 16 to 1 in total length. Females are slightly smaller.

The head is oval. The eyes are round and protruding. The antennae are thread-like and longer than the wings. They are attached close together high on the face. The space between them is narrower than the length of the basal segment of the antennae. The forehead does not project forward between the antennae.

The thorax, abdomen, wings, and femurs are pale grass green. The body is to 1 long. The upper side (dorsum) does not have a brown stripe.

The wings are 1to 17 16 long. The forewing is longer than the abdomen and longer than the hindwing. It is narrow, more than four times but less than six times as long as wide at its widest point. It is green, rarely with black marks, rounded at the tip, and has a single shallow angle near the base.

The front legs are much shorter than the hind legs. The femur of the hind leg is long, extending to the last (distal most) quarter of the outer wing.

On the male a structure below the genitalia (subgenital plate) is conspicuous, elongated, Y-shaped, and arched upward.

On the female the ovipositor is abruptly curved upward.

Curve-tailed bush katydid (S. c. curvicauda) range extends into Minnesota. It is relatively large, 1 to 1in total length.

Northern curve-tailed bush katydid (S. c. borealis) may occur in Minnesota. It is relatively small, 17 16 to 19 16 in total length.
