Differential grasshoppers are large plant-feeding insects that commonly inhabit agricultural areas, grasslands, and gardens throughout North America. They are among the most recognizable grasshopper species due to their relatively large size and distinctive markings. These insects can cause damage to crops, ornamental plants, and lawns when populations become high.
Quick Facts
- Scientific Name: Melanoplus differentialis
- Family: Acrididae
- Habitat: Grasslands, gardens, farms, and roadside vegetation
- Diet: Leaves, grasses, crops, and garden plants
- Status: Agricultural and garden pest
Identification
Differential grasshoppers are large insects typically measuring between 1.5 and 2 inches long. They are yellowish to brown in color with dark chevron-shaped markings on their hind legs. Their wings extend beyond the abdomen and allow them to fly short distances when disturbed.
Like other grasshoppers, they possess powerful hind legs that allow them to jump long distances.
Distribution
This species occurs widely across the United States and southern Canada. They are especially common in the Midwest and Great Plains where crop production provides abundant food sources.
Life Cycle
Differential grasshoppers undergo incomplete metamorphosis with egg, nymph, and adult stages. Eggs are laid in the soil during late summer and remain there over winter. Nymphs hatch in spring and gradually develop wings as they grow.
Pest Status
Large populations can defoliate crops such as soybeans, corn, vegetables, and alfalfa. They may also damage garden plants and landscaping.
Prevention
- Remove tall weeds and unmanaged vegetation near gardens
- Encourage birds and natural predators
- Monitor populations during spring and summer
Control
Early detection and integrated pest management techniques are the most effective methods for controlling grasshopper populations before they reach damaging levels.
