Andricus weldi

Andricus weldi is a of in the Cynipidae. Like other members of this diverse family, it induces the formation of specialized on oak . The species was named in honor of Lewis H. Weld, a prominent cynipidologist who authored foundational works on gall wasps of the eastern United States. Specific details regarding its gall , host associations, and biology remain limited in the available literature.
