About Chortophaga australior Rehn & Hebard, 1911
Chortophaga australior Rehn & Hebard, 1911, also known as the green-striped grasshopper, displays the following size variation by sex: adult males range from 23 to 30 mm, while adult females range from 28 to 38 mm. Females are typically green and males are typically brown, though both sexes show color variation. This grasshopper is found in both North America and Central America. Its range extends from British Columbia to the Gulf of Mexico, mostly east of the Rocky Mountains, and stretches south to Costa Rica. Green-striped grasshoppers live in relatively moist areas of short grass, including common sites like roadsides and hay meadows. Brood number varies by region: this species is single-brooded in the North and west of the Great Plains, but multiple-brooded in the Southeast. In the single-brooded parts of its range, females lay eggs early in the summer. These eggs hatch later the same summer. Nymphs molt three to four times before winter, survive the winter, then molt one or two more times to reach adulthood. The closely related C. viridifasciata is often the first grasshopper to appear in early spring, due to its overwintering nymph stage. Green-striped grasshoppers typically go through five instars during their development.
