Amphibolips is a of gall wasps in the Cynipidae, first described by Reinhard in 1865. The genus contains approximately 57 described , with additional undescribed species known. All members are native to the Americas and are specialized gall inducers, primarily on oaks (Quercus spp.).

Identification

Amphibolips are distinguished from other cynipine gall wasps by a combination of morphological features including reduced wing venation, specific tarsal segment proportions, and characteristic gall morphologies on oak . Species-level identification requires examination of gall structure, host oak species, and detailed morphological analysis of specimens.

Habitat

Associated with oak-dominated forests and woodlands, wherever Quercus occur.

Distribution

Native to the Americas; distribution records include the United States (including Vermont) and presumably extending throughout the range of native oak in North, Central, and South America.

Host Associations

Quercus - gall inductionAll known induce galls on oaks; specific associations vary by species

Ecological Role

Gall induction modifies oak tissue development, creating specialized microhabitats that support complex including , , and hyperparasitoids.
