The Black-sided Pygmy Grasshopper is one of the pygmy locusts, so called because they are the smallest representative of the family. It is found in eastern and central North America (including southern Canada), west to Arizona and Colorado, and south into Mexico and Central America.
It lives in wet, sedgy meadows, especially on sandy soil, and deciduous and coniferous forests. It feeds upon plant matter such as algae, lichen, mosses, young grasses, germinating seeds of plants.
It is also called Sedge Grouse Locust.
