Ceroptres
Ceroptres is a genus of gall wasps in the tribe Ceroptresini (Cynipidae). The genus includes 43 described species, of which 40 are known from North America. Ceroptres species are inquilines: they do not induce their own galls but instead oviposit into galls formed by other organisms. Host galls are primarily those induced by other gall wasps (Cynipini), though some species use galls formed by gall midges (Cecidomyiidae). Species are host specialists, typically associated with a single host gall species or with several phylogenetically or ecologically related galls.
