Treehoppers (Buffalo)


  • Eggs: Females lay eggs masses under the bark of trees in early fall. The eggs hatch in spring.
  • Nymphs: Nymphs are green and very spiny. They drop to the ground and feed on weeds and grasses until they reach maturity in August.
  • Adults: Adult treehoppers are strange looking creatures; some resemble miniature dinosaurs; others resemble bumps or thorns. After mating, females fly to trees to lay their eggs and remain there until cold temperatures kill them.

Identifying infestations:

  • Weakened plants: Plants may appear weakened since treehoppers feed by inserting their sharp, needle-like mouthparts into plant tissues and sipping cell fluids.

IPM Toolkit:

  • Preventive tools:
    • Remove excess green organic matter (weeds and grasses) where nymphs feed.
  • Physical tools: Not applicable.
  • Biological tools: Not applicable.
  • Least toxic chemical tools:
    • Apply Pyrethrum and/or Rotenone according to label directions to control large infestations.
