The description of Zapatella davisae, new species, (Hymenoptera: Cynipidae) a pest gallwasp of black oak (Quercus velutina) in New England, USA
Proceedings of the Entomological Society of Washington 118 (1), 14-26
Abstract: Many species of gall wasp (Cynipidae) essentially co-exist with their host oak tree species. Occasionally, the association becomes destructive to the tree, as is the case with Zapatella davisae, new species. This species is a twig galler, and as such, in the cases of heavy infestation, cause flagging, leaf clumping, and dieback of branches and twigs. Historical records of other species of Zapatella suggest that members of this genus have a checkered record with respect to damaging their host plants in North America, and these data are summarized here.
