Chortophaga viridifasciata, the green-striped grasshopper, is a species of band-winged grasshopper in the family Acrididae. It is found in Central America and North America, ranging from British Columbia to the Gulf of Mexico (mostly east of the Rocky Mountains), south to Costa Rica.
Green-striped grasshoppers inhabit relatively moist areas of short grass, such as roadsides and hay meadows. The green-striped grasshopper is single-brooded in the North and west of the Great Plains but is multiple-brooded in the Southeast.
In the single-brooded range, green-striped grasshoppers' eggs are laid early in the summer season. These eggs hatch later in the same summer. The nymphs will molt three to four times before winter. The nymphs survive through the winter and then molt one or two more times to reach adulthood. C. viridifasciata is often the first grasshopper to appear in early spring because of its overwintering.
Green-striped grasshoppers typically have five instars during development. Their size ranges from 23 to 30 mm for males and 28 to 38 mm for females. Females are typically green and males are typically brown but there is... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green-Striped Grasshopper is recorded against all the insects logged in Calgary (83 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
