Life cycle and habits

The wingless grasshopper normally has only one generation per year although under some unusual conditions there may be a second generation.

Eggs are laid in small cylindrical pods (see Figure 2). Each pod contains 10-15 eggs and is deposited 1-2cm below the surface of the soil.

Partial development of the eggs occurs after laying, before a dormant state (diapause) begins. The egg is carried through winter in this condition, and requires prolonged exposure to low temperatures before development recommences in spring in response to increasing soil temperature.
