Life Cycle Of Grasshoppers

  • A grasshopper begins its life as an egg. The mother grasshopper lays the egg during the midsummer time and is seen one or two inches under the sand or in the leaf litter.
  • The eggs will remain in its place for about 10 months and once winter sets in, they will start to hatch.
  • This is the second stage of the grasshopper’s life cycle and is known as the nymph. This is the stage when a younger grasshopper gets to see the outside world.
  • The nymphs are called molts and look like the adult grasshoppers with the exception that they do not have wings and no reproductive organs.
  • The nymphs will now go through five different stages of growth called instars before it develops into an adult grasshopper.
  • Each instar stage will see the growth of the wings in a gradual manner and the shedding of the cuticle skin.
  • The nymphs will feed on the soft plant foliage and succulent to survive. It will take 5 to 6 weeks for the nymphs to mature into an adult grasshopper.
  • The adult grasshopper is very active than the nymph and it will start to fly and hunt from predators.
