• Neuroterus

  Neuroterus is a genus of gall wasps in the family Cynipidae that induce galls on oak species. The genus was first described by Theodor Hartig in 1840. Some species, notably N. saltatorius, produce distinctive 'jumping galls' that detach from the host plant and move along the ground due to larval activity within. Like other oak gall wasps, Neuroterus species exhibit complex life cycles with alternating sexual and asexual (agamic) generations, with each generation typically inducing galls on different parts of the host plant.

  Neuroterus niger is a species of gall wasp in the family Cynipidae that induces distinctive galls on oak leaves. This species exhibits an alternating sexual and asexual life cycle, with different generations producing different gall types. The asexual generation creates small, spherical galls that detach from leaves and fall to the ground, where the larva's movements cause the gall to jump—giving rise to the common name "jumping gall." The sexual generation produces inconspicuous leaf galls. The species has been documented across much of eastern and central North America.

• Neuroterus saltarius

  Jumping Gall Wasp

  Neuroterus saltarius is a species of gall wasp in the family Cynipidae, commonly known as the jumping gall wasp. It induces distinctive leaf galls on oak trees that detach from the plant and fall to the ground. The developing larva inside the fallen gall can cause the gall to jump when it moves, a unique behavioral trait that gives the species its common name. This species is part of the diverse Neuroterus genus, which contains many oak-associated gall wasps with complex life cycles.

• Neuroterus saltatorius

  Jumping Gall Wasp

  Neuroterus saltatorius, commonly known as the jumping gall wasp, is a North American oak gall wasp in the family Cynipidae. The species is notable for producing small, round galls that detach from leaves and exhibit a distinctive jumping behavior caused by larval movements. It has a complex life cycle with alternating bisexual and parthenogenetic generations, each producing different gall types on oak hosts.
