Differential Grasshopper

Differential Grasshopper

Melanoplus differentialis
Family: 
Acrididae (short-horned grasshoppers) in the order Orthoptera (grasshoppers, katydids, crickets)
Description: 

Relatively large grasshoppers that vary somewhat in coloration and may be green, brownish-green or olive green. The femurs of the hind legs have a black herringbone pattern, and the tibias are usually yellow with black saw-toothed spikes.

Size: 
Length: to 2 inches.
Habitat and conservation: 
Found in a wide variety of habitats, including open fields, gardens, grasslands, meadows, prairies, roadsides, and lands along ponds and streams. Originally it lived only in wet meadows and creek bottomlands, but with the spread of farms, it has become a pest of many food crops. Population numbers fluctuate from year to year.
Foods: 
The adults and nymphs feed on a wide variety of grasses and other leafy plants. They also eat crops, including corn, soybeans, alfalfa, cotton, vegetables, small grains and the leaves of fruit trees. When they run out of food in one area, the adults can travel up to 10 miles in a day in search of more food.
Distribution in Missouri: 
Statewide.
Status: 
Common and abundant.
Life cycle: 
Mating takes place late in the summer or in early fall. The female uses her ovipositor to press long eggs masses into the soil. She is capable of laying up to 8 egg masses that contain 25 eggs each. The eggs overwinter, and the nymphs emerge the following spring. It takes the nymphs approximately two months to reach adulthood.
Human connections: 
At times, differential grasshoppers occur in large enough populations to cause severe damage to agricultural crops. Remember, however, that one of their favored food plants is giant ragweed!
Ecosystem connections: 
They are an important component in the food chain for many animals, including foxes, raccoons, opossums, squirrels, amphibians, lizards, snakes, birds, turtles, bats and many predatory spiders and insects.
