Grasshopper Lifecycle
The lifecycle of the bigheaded grasshopper, Alucara ellliotti (Thomas).
- During summer in bare spots of grassland the female deposits at intervals batches of eggs.
- As soon as the eggs are laid, they begin embryonic development and reach an advanced stage in which they enter diapause and pass the winter.
- In spring the eggs complete embryonic development and hatch.
- The young grasshopper sheds a serosal skin, the exoskeleton hardens, and the nymph begins to feed and grow.
- After molting five times and developing through five instars in 30-40 days, it becomes an adult grasshopper with functional wings.
- The adult female matures groups of six to eight eggs at a time and deposits them in the soil at intervals of three to four days for the duration of her short life.
