Black field earwig
Nala lividipes
Adults are 15 mm long, shiny black with a flattened body and a pair of curved pincers at the end of the body. Nymphs resemble adults but are wingless and paler.
The black field earwig eats newly sown and germinating seed and the roots of crops, resulting in poor establishment. Feeding on secondary roots may cause the plants to fall over as they get larger.
