Grasshoppers are insects of the order Orthoptera and are characterized by their jumping ability, thanks to their long and muscular hind legs. Their robust body and chewing mouthparts allow them to feed on a wide variety of vegetation. Females lay their eggs on the ground, generally in sunny areas with loose soil. These eggs remain dormant during the winter and hatch with rising temperatures in spring. The nymphs emerge and go through several molts until they reach the adult phase, a process that can last weeks or months, depending on the species and environmental conditions. During the juvenile stages, they do not have wings and move around by walking or jumping, actively feeding. Once they reach adulthood, they can move long distances and form swarms when ecological conditions are favorable. These massive migrations drastically increase their destructive capacity on crops and green areas. Some species, such as lobsters, can change their behavior from solitary to gregarious, multiplying their invasive and harmful potential.
