The cherry gall wasp (Cynips quercusfolii) is a hymenopterous insect of the family Cynipidae widespread throughout Europe and Asia Minor, that produces spherical leaf galls on various species of oak. The galls are mostly to be seen between July and October and are attached to either the main leaf vein or one of the stronger side veins by a very short stem. The gall is at first green-yellow in colour later turning yellow and then red on the side facing the sun before becoming brown and wrinkled. The larvae develops within the gall, feeding upon the gall tissue and pupates within the gall. Two generations appear within a year, the first all female that reproduce parthenogenetically the second male and female.

The Cola-nut Gall Wasp (Andricus lignicola) a hymenopterous insect of the family Cynipidae widespread through almost all Europe. The Cola-nut Gall Wasp produces very firm, woody, spherical galls which grow from axillary and sometimes terminal buds on the branches of various species of oak tree.

The Common Spangle Gall Wasp (Neuroterus quercusbaccarum formerly known as Neuroterus lenticularis) is a hymenopterous insect of the family Cynipidae found in Europe, Asia Minor and North Africa. The wasp develops on Oak trees, producing two different galls: a lens-shaped gall of about 5 mm diameter grown from July onwards on the underside of leaves, and a second generation of spherical juicy galls of about 7 mm diameter produced on the underside of the leaves and in male catkins during the spring.

Gall-fly is a name for several hymenopterous insects of the family Cynipidae, which form galls, each species preferring a different plant. The gall is due to an irritating fluid which the insect deposits on the plant along with its egg. The large galls at the base of oak leaves are produced by the Cynips quercus baccarum, a fly of a brown colour, with blade antenna, chestnut-brown legs, and white wings. The small galls on the under surface of oak leaves are due to another species, Cynips quercus folii, those on the stems of oaks to Cynips terminalis.

The Green Velvet Bud Gall Wasp (Cynips longiventris) is a is a hymenopterous insect of the family Cynipidae widespread in central, western, south-western Europe, southern Russia and the Middle East. The Green Velvet Bud Gall Wasp produces a white gall with brown stripes on various species of oak, within which the larvae develops and pupates, the adult emerging in December.

The Knopper Gall Wasp (Andricus quercuscalicis) is a hymenopterous insect of the family Cynipidae widespread in southern, western and central Europe and Asia Minor and since first being recorded in Britain in 1959 is now widespread and common in Britain. The Knopper Gall Wasp Produces two types of gall, one type are produced on acorns and are green and sticky later becoming brown and hard, and irregular in shape. The second generation of galls are produced in the axis of the male catkins of Turkey Oaks.

The Marble Gall Wasp (Andricus kollari) is a hymenopterous insect of the family Cynipidae common in central, southern and western Europe, and less common but found in the British Isles, North Africa and Asia Minor.

The Oak Apple Gall Wasp (Biorhiza pallida) is a hymenopterous insect of the family Cynipidae. The adult wasp reaches a length of between 1.9 and 2.3 mm, the larvae measuring between 3.5 and 6 mm in length. The female wasp injects her eggs into a bud on the oak branch which develops into a gall in which the larvae develop, later pupating within the gall before emerging as an adult wasp.

The Silk-button Spangle Gall Wasp (Neuroterus numismalis) is a small hymenopterous insect of the family Cynipidae found in Europe and Asia Minor. The Silk-button Spangle Gall Wasp produces two distinct types of gall on the leaves of the oak tree. The most conspicuous gall is a red coloured, cup-shaped gall of about 3 mm diameter found on the underside of the leaves which over-winter on the ground attached to fallen leaves. The larvae inside these galls pupate and emerge in March, an entire generation of female wasps. These female wasps lay their eggs in the large oak buds, and these larvae pupate to emerge as a second generation of both male and female wasps in May or early June. The females of this second generation lay their eggs on the underside of leaves, causing the cup-shaped galls to form.
