are generally elongated insects with narrow, leathery forewings; large, membranous flying wings; and chewing mouthparts. The hind legs are large and adapted for jumping. They vary in color from greenish-yellow to gray to brown to brownish-black. All vary in size up to 1 1/4-inches long when fully grown. Immature grasshoppers are smaller and closely resemble adults but do not have wings. Facts:
- The scientific names for grasshoppers that attack blueberry are Melanoplus differentials and Camnula pellucida.
- Most grasshoppers spend the winter in the egg stage in the soil.
- The time for egg laying varies with the species of grasshopper.
- Eggs are placed well below the surface of the ground, preferably in firm, unbroken soil along roadsides or edges of fields or in open areas of managed fields.
- After the eggs hatch, young grasshoppers, called nymphs, push to the surface of the ground and begin feeding on the nearest vegetation.
- Grasshoppers mature to the adult stage and continue to feed on foliage and berries.
- Both young grasshoppers and adults feed by chewing foliage and by biting and chewing on berries.
- Feeding damage is often detected later as a calloused scar on the fruit.
