Platycotis vittatus

Platycotis vittatus

Also known as Oak Treehopper

Oak treehoppers display striking morphological variation, occurring in both hornless varieties and forms sporting a long, forward-pointing thorn atop the thorax, often decorated with vibrant longitudinal stripes. Females exhibit devoted maternal care, guarding their egg clusters on oak twigs and defending the newly hatched nymphs against predators. As the young feed on plant sap, they excrete honeydew that frequently attracts mutualistic ants, which protect the cluster in exchange for the sugary reward.

Responsible observation
  • Twig inspection: Search the underside of tender oak branches in spring to spot brooding females and clusters of striped nymphs.
  • Follow ant trails: Watch for worker ants actively patrolling tree limbs, as they often lead directly to honeydew-producing aggregations.
