Mole Cricket ID

General Description

Mole crickets are cylindrical-bodied insects about 3-5cm long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and some of the species are considered serious sub-surface pest in turf. Most damages were caused by tunnelling and resulted to loss of turf but some species of Mole crickets feed on turf plant and roots.

Habitat:

  • Often found in golf greens, tees and fairways and othermanaged turf area, especially in wet & sandy area.
  • They usually come to the surface evenings and at night, and is attracted to light sources.

 

Life Cycle and Development Stage

  • Incomplete metamorphosis with egg, nymph and adult. Nymphs resemble adults but do not have developed wings.
  • Depending on species and weather conditions, life cycle may last from 1- 3 years and some species will have more than 1 generation per year.

  • Color patterns on the protonum are also useful in separating species.

Damage

  • Disruption in playing surface through tunnelling and often lead to desiccated turf by severing roots and uprooting the grass.
  • Species like Tawny, Southern, Oriental and Short-winged are more damaging to turf as they feed on turf plants and roots while other species feed predominately on insects, earthworms, and other invertebrates.
