Andricus dimorphus, also called the clustered midrib gall wasp, is a species of oak gall wasp in the family Cynipidae. Galls in which the larvae live and feed are formed in clusters along the midrib on the underside of oak leaves.[1]
Range
[edit]This species has been found throughout central and eastern North America where its host species occur.[1][2][3]
Description
[edit]Confirmed hosts of the clustered midrib gall wasp are white oak species, including Quercus macrocarpa, Q. alba, Q. prinoides, and Q. bicolor.[1][2] Clusters of up to 50 globular (but with a pointed base), red-brown galls are formed along the midrib on the underside of leaves beginning in late summer.[1][2][3] The galls readily detach from the leaf, particularly when mature.[1][2][3] Adults emerge from the galls the following year.[2][3] Inquilines and parasitoids may inhabit the galls.[4]
Taxonomy
[edit]This species was first described by William Beutenmuller in 1913 with the name Cynips dimorphus.[2] According to Clarence Gillette, William Ashmead had already used this name by 1889 for a species that produces galls similar to those of Beutenmuller's Cynips dimorphus.[5] This species was later transferred to the genus Adleria which itself was subsequently included within Andricus.[6]
