Green grasshoppers with black herringbone markings on their hind femora. I spotted these two mating (male is smaller and is on dorsal surface of female). On the lower left, there is a small brown moth - this moth is a Purple Carrot-seed Moth (Depressaria depressana).
The differential grasshopper is a species of grasshopper belonging to the genus ''Melanoplus'' found throughout northern Mexico, central United States and southern Ontario, Canada. It is considered a pest in most of its range.
