Schistocerca americana is a species of grasshopper in the family Acrididae known commonly as the American grasshopper and American bird grasshopper. It is native to North America, where it occurs in the eastern United States, Mexico, and the Bahamas. Occasional, localized outbreaks of this grasshopper occur, and it is often referred to as a locust, though it lacks the true swarming form of its congener, the desert locust (S. gregaria).
The adult male of the species is up to 4.5 cm (1.8 in) long, and the adult female may reach 5.5 cm (2.2 in). The body of the adult is generally yellow-brown in color and the wings are pale with large brown spots. The nymphs are different in appearance. They change color as they mature and their coloration is a polyphenic trait – influenced by environmental conditions, producing multiple forms from one genotype. This is not uncommon among grasshoppers. In this species, the coloration of the nymphs is especially influenced by temperature. Nymphs are various shades of green, yellow, or red, usually with a pattern of black markings. They are often red at lower temperatures, but at higher temperatures, only green and yellow shades occur.... Wikipedia →

GBIF citizen-science records
It is estimated from how often the American Bird Grasshopper is recorded against all the insects logged in Dallas (150 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.
