Tetrix japonica is a tiny East Asian grasshopper, about 0.3–0.6 in (7.4–15.3 mm) long, with no documented U.S. range. Its gray, brown, black, and whitish forms make color alone a poor clue for identification.
Appearance
Appearance
The body is sturdy, and the shield-like upper surface of the thorax extends backward. Two to six slanting dark marks may cross the back, but both color and pattern vary widely.
Seasonal forms
Some individuals have a longer rear projection and longer hind wings. Close-up photos from above and from the side are more useful than color for separating similar species.
