The oak marble gall is frequently conflated with the oak apple gall, caused by another gall wasp, Biorhiza pallida. Oak marble galls are also known as the bullet gall, oak nut or Devonshire gall. [5] The developing spherical galls are green at first, brown later, and mature in August. Each gall contains a central chamber, with a single female ...
Cynipini is a tribe of gall wasps. These insects induce galls in plants of the beech and oak family, Fagaceae. [1] They are known commonly as the oak gall wasps. [2] It is the largest cynipid tribe, with about 936 [3] to 1000 [2] recognized species, most of which are associated with oaks. [2] The tribe is mainly native to the Holarctic. [3]
The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
Jumping oak galls are caused by a very tiny, native, stingless wasp (Neuroterus sp.) which lays eggs in leaf buds. As the leaf develops, pinhead-sized galls, also referred to as abnormal plant ...
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 .
Atrusca brevipennata, formerly Andricus pellucidus, also known as the little oak-apple gall wasp, is a locally common species of cynipid wasp that produces galls on oak trees in North America. [1] The wasp oviposits on shrub live oak and Gambel oak leaves. [1] The larval chamber is at the center of the gall, connected to the husk by slender ...
Cola-nut gall cut open to show the unilocular cavity Oak marble galls showing two stunted and two normal-sized examples. The galls are found in small groups, which however do not coalesce, helping to prevent mis-identification with the oak marble gall (Andricus kollari), in addition the shape is ovoid rather than spherical and it is scaly rather than smooth.
Disholcaspis quercusmamma, the oak rough bulletgall wasp, is a species of gall wasp in the family Cynipidae. [1] 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 .
