Ceroptres

Hartig, 1840

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

Habitat

Ceroptres inhabits galls formed by other organisms on plants. Host galls are found on trees and other vegetation, with oak galls (Cynipini) being the primary host structure.

Distribution

North America (40 of 43 ); records from Pennsylvania, Texas, and other regions. Three species occur outside North America. GBIF records indicate presence in Denmark, Norway, and Sweden.

Host Associations

  • cecidomyiid midge galls - Used by some Ceroptres ; two species reared from these galls
  • oak galls (Cynipini) - Primary galls for most Ceroptres
  • single host gall species or related galls - associated with phylogenetically or ecologically related galls

Behavior

lifestyle: females oviposit into existing galls induced by other organisms. Larvae inhabit and feed within these galls, causing the gall to enlarge and form locularities (larval chambers).

Ecological Role

in gall ; modifies galls by inducing enlargement and formation of additional larval chambers.
