- Mole crickets hibernate as adults or 3rd-instar nymphs, deep in the soil, from a few centimeters to 1 metre. Hibernating forms become active in the spring and form tunnels some close to the soil surface, others at considerable depths. Oviposition and breeding chambers are also built, from which the summer generation originates.
- Mole crickets sometimes wander above ground or fly in relatively large swarms, especially in warm summer nights.
Females excavate a nest chamber at a depth of 30-40 cm. In each chamber - with a diameter of 6-10 cm - 200 to 300 eggs are laid. They hatch 20 days later. Nymphs pass through two moults. In October they excavate their own tunnels and hibernate.
Mole crickets feed on earthworms(Lumbricidae), soil-inhabiting insect larvae and roots of garden and kitchen-garden plants, as well as those of grasses (*) , potatoes, etc. Mole crickets prefer light, fresh soils with high organic matter content where food is available and tunnels can be excavated easily.
Occasionally, mole crickets wander above ground causing then extensive damage in plant beds.
