Common Name: Differential Grasshopper
Order: Orthoptera Family: Acrididae Pest Status: Grasshoppers can occur in large groups and can cause significant defoliation and crop damage when weather conditions are dry. Appearance: Adults can grow up to 1 3/4-inches long. They have a shiny brown-yellow body with yellow or red antennae. The hind legs are yellow with characteristic black v-shaped markings. Life Cycle: Eggs generally overwinter after they are deposited two inches deep in the soil. Nymphs hatch from the eggs in the spring and develop through five or six instars. Nymphs become adults within two months. Where to Collect: Differential grasshoppers live in fields, open woods, and edges of ponds, streams, and lakes. They can best be collected with a net after they fly or jump. |
