Neuroterus saltatorius, also known as the jumping gall wasp, is a species of oak gall wasp. It is found in North America, where it induces galls on a variety of oak trees, including Oregon oak, valley oak, California scrub oak, blue oak, [1] [2] and leather oak. [3]

Contents

Like other oak gall wasps, it has two generations: a bisexual generation, and a parthenogenetic female generation. The all-female generation's galls appear in late spring. These round, 1 mm across galls occur on the underside of leaves, and eventually detach and fall into the leaf litter. Adults emerge early the following spring and lay eggs for the bisexual generation. This generation induces galls that are integral to the leaf. [2] [1]

Adult wasps are .75 millimetres (0.030 in) long, brown and/or black, with reddish legs. [1]

Jumping behavior

Once they have fallen to the ground, the unisexual galls of Neuroterus saltatorius "jump" due to the movements of the larvae inside. [2] A study at University of California, Santa Cruz found this behavior happened during dry weather at temperatures between 20–40 °C (68–104 °F). [4] This behavior might help the galls dig deeper into the leaf litter for protection from the elements or predators. [2]

Effects on trees and other species

The presence of Neuroterus saltatorius does not cause significant damage to their host trees. However, the parthenogenetic generation of galls can damage leaves when in high concentrations. On Quercus garryana , this can potentially have a negative effect on the butterfly Erynnis propertius , whose larvae also feed on Q. garryana leaves. [1] [5]

<span class="mw-page-title-main">Gall wasp</span> Family of wasps

Gall wasps, also traditionally calledgallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.

<span class="mw-page-title-main">Oak apple</span> Gall found on oak trees

An oak apple or oak gall is a large, round, vaguely apple-like gall commonly found on many species of oak. Oak apples range in size from 2 to 4 centimetres in diameter and are caused by chemicals injected by the larva of certain kinds of gall wasp in the family Cynipidae.

<i>Cydia saltitans</i> Species of moth

Cydia saltitans or jumping bean moth is a moth from Mexico that is most widely known as its larva, where it inhabits the carpels of seeds from several related shrubby trees, mainly Sebastiania pavoniana or Sapium biloculare. These seeds are commonly known as Mexican jumping beans.

<i>Andricus kollari</i> Species of insect

Andricus kollari, also known as the marble gall wasp, is a parthenogenetic species of wasp which causes the formation of marble galls on oak trees. Synonyms for the species include Cynips kollari, Andricus quercusgemmae, A. minor, A. indigenus and A. circulans.

<i>Andricus foecundatrix</i> Species of wasp

Andricus foecundatrix is a parthenogenetic gall wasp which lays a single egg within a leaf bud, using its ovipositor, to produce a gall known as an oak artichoke gall, oak hop gall, larch-cone gall or hop strobile The gall develops as a chemically induced distortion of leaf axillary or terminal buds on pedunculate oak or sessile oak trees. The larva lives inside a smaller hard casing inside the artichoke and this is released in autumn. The asexual wasp emerges in spring and lays her eggs in the oak catkins. These develop into small oval galls which produce the sexual generation of wasps. A yew artichoke gall caused by the fly Taxomyia taxi also exists, but is unrelated to the oak-borne species. Previous names or synonyms for the species A. fecundator are A. fecundatrix, A. pilosus, A. foecundatrix, A. gemmarum, A. gemmae, A. gemmaequercus, A. gemmaecinaraeformis and A. quercusgemmae.

<i>Neuroterus</i> Genus of wasps

Neuroterus is a genus of gall wasps that induce galls on oaks in which the wasp larvae live and feed. Some species produce galls that fall off the host plant and 'jump' along the ground due to the movement of the larvae within.

<i>Neuroterus quercusbaccarum</i> Species of wasp

The common spangle gall on the underside of leaves and the currant gall on the male catkins or occasionally the leaves, develop as chemically induced distortions on pedunculate oak, or sessile oak trees, caused by the cynipid wasp Neuroterus quercusbaccarum which has both agamic and bisexual generations.

<i>Neuroterus albipes</i> Species of wasp

Neuroterus albipes is a gall wasp that forms chemically induced leaf galls on oak trees which has both bisexual and agamic generations and therefore forms two distinct galls, the smooth spangle gall and Schenck's gall. Neuroterus laeviusculus and Spathegaster albipes are previous binomials found in the literature.

<i>Neuroterus numismalis</i> Species of wasp

Neuroterus numismalis is a gall wasp that forms chemically induced leaf galls on oak trees. It has both bisexual and agamic (parthenogenetic) generations and forms two distinct galls on oak leaves, the silk button gall and blister gall. The galls can be very numerous with more than a thousand per leaf.

<i>Neuroterus anthracinus</i> Species of wasp

Neuroterus anthracinus is a widely distributed gall wasp that forms chemically induced leaf galls on oak trees. N. anthracinus has both sexual and agamic generations and in consequence forms two distinct galls, the oyster gall and April-bud gall.

<i>Biorhiza pallida</i> Species of wasp

Biorhiza pallida, also known as the oak apple gall wasp, is a gall wasp species in the family Cynipidae. This species is a member of the tribe Cynipini: the oak gall wasp tribe. Cynipini is the tribe partially responsible for the formation of galls known as oak apples on oak trees. These are formed after the wasp lays eggs inside the leaf buds and the plant tissues swell as the larvae of the gall wasp develop inside. This wasp has a widespread distribution within Europe.

<i>Feron kingi</i> Species of wasp

Feron kingi, the red cone gall wasp, is a species of gall wasp in the family Cynipidae.

<i>Cynips douglasii</i> Species of wasp

Cynips douglasii, the spined turbaned gall wasp, is a species of gall wasp in the family Cynipidae. It induces galls in valley oaks, blue oak, and California scrub oak. The leaf galls induced by the parthenogenic, unisexual generation in summer are noted for their spines and can be white, purple, or pink. They can be up to 10 millimetres (0.39 in) wide and 15 millimetres (0.59 in) high. Adult females emerge from these galls in winter. The bisexual generation induces rounder, green bud galls in spring.

<i>Cynips quercusechinus</i> Species of wasp

Cynips quercusechinus, the urchin gall wasp, is a species of gall wasp in the family Cynipidae. It induces galls in the leaves and leaf buds of blue oak and scrub oak. Like other oak gall wasps, it has two generations: a bisexual generation, and a parthenogenic female generation. In spring, the hatching bisexual generation produces hollow green galls in leaf buds. In summer, the unisexual generation induces its galls, which are red or pink and resemble sea urchins, on the undersides of leaves. These galls are about 10 millimetres (0.39 in) in diameter. The galls fall with the leaves in autumn, and the larvae inside of them emerge as adults in the spring and lay their eggs.

<i>Disholcaspis quercusmamma</i> Species of wasp

Disholcaspis quercusmamma, the oak rough bulletgall wasp, is a species of gall wasp in the family Cynipidae. The quercus in its name is the genus name for oak, while "mamma" is Latin for "breast", presumably a reference to the "nipple" on the gall.

<i>Amphibolips quercuspomiformis</i> Genus of insects

Amphibolips quercuspomiformis, also known as the apple gall wasp or live oak apple gall wasp, is a species of gall wasp. It induces galls in coast live oak and interior live oak trees. Like many gall wasps, it has two alternating generations which induce differing galls: an all-female parthenogenic generation, and a bisexual generation. The galls formed by the unisexual generation in summer are spherical, up to 40 mm in diameter, and covered with short spines. They form on stems and are green or red when new, then turn brown. The galls formed by the bisexual generation in spring are small, shaped like toadstools, and occur on leaves.

<i>Andricus confertus</i> North American gall-inducing wasp

Andricus confertus, the convoluted gall wasp, is a fairly common species of cynipid wasp that produces galls on oak trees in California in North America. This gall, with its pink, brain-like appearance, is actually a cluster of galls. In summer, parthenogenetic female larvae induce these galls on the underside of valley oak leaves, along the midrib. Adult wasps emerge the following spring. These adult females are brown with lighter markings, and are 2.5 millimetres (0.098 in) in length.

<i>Neuroterus fragilis</i> Species of wasp

Neuroterus fragilis, also known as the succulent gall wasp, is a species of oak gall wasp. It induces galls in oak trees in California, including leather oak, California scrub oak, blue oak, and valley oak. Adults are small, 0.7–1.2 millimetres (0.028–0.047 in), with yellow legs. The galls it induces are 10–30 millimetres (0.39–1.18 in), and present as swellings of the petioles and midribs of oak leaves. In this species of oak gall wasp, only the spring bisexual generation, consisting of both males and females, is known. However, an all-female parthenogenic generation in summer, which most oak gall wasps have, is possible.
