Gall wasps, also traditionally called gallflies, 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.

Jan 12, 2023 · Succulent spring galls on oak buds, flowers, and leaves produce fully winged, short-lived males and females. The larvae in the more solid, autumnal galls metamorphose in the fall and depending on species the adults, which are all agamic females, may emerge in late fall (as in Disholcaspis spp.) or stay in the galls over the winter.

gall wasp, (family Cynipidae), any of about 1,300 species of small wasps that are notable for their ability to stimulate the growth of galls (tissue swellings) on plants. Some gall wasp species are gall inquilines, meaning they do not cause the formation of …

These are the results of a tiny parasitic wasp called a gall wasp or cynipid. Usually, the plant is not harmed a great deal, and the relationship helps the wasp to carry on its life functions using the modified plant as food. Galls are caused by the reaction of a plant to specialized growth hormones exuded by the larva of these wasps.

Common Name: Gall Wasps. Description: Cynipids are very small, black wasps whose larvae induce the formation of galls in their host plants. Adults can be recognized by their humpbacked profile, distinctive wing venation, and compressed abdomen with telescoped segments toward the rear. Order: Hymenoptera.

A variety of different species of tiny, non-stinging wasps in the family Cynipidae (gall wasps) create galls (deformations) in the leaves of oak. The good news is, while these species may at times change the appearance of oak leaves to a very noticeable extent (that is perhaps alarming to some), they very rarely if ever require management .

Jun 17, 2019 · Gall wasps (family Cynipidae) are likely the most common gall-making insects. Here's more about gall wasps, and which plants they affect.

Description: Two kinds of galls are produced by this wasp. The most notable are produced by the asexual generation that are spherical, corky, 1/8 to 1 inch in diameter and appear on twigs and branches of live oak in late summer and early fall. When first formed, they are pink to pinkish brown and the yellow-green tissue inside is moist and soft.

May 20, 2015 · Gall wasps (Cynipidae) represent the most spectacular radiation of gall-inducing insects. In addition to true gall formers, gall wasps also include phytophagous inquilines, which live inside the galls induced by gall wasps or other insects.

On roses, 30 or so species of cynipid gall wasps in the genus Diplolepis initiate gall development on the leaves, stem, bud, or root of their host plant depending upon the host plant species. All of these species of wasps seem to be parthenogenetic, or able to reproduce asexually.
