Ceroptres species are : they do not induce their own 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 (). Species are host , typically associated with a single host gall species or with several phylogenetically or ecologically related galls.

Habitat

Ceroptres inhabits 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
  • oak galls (Cynipini) - Primary for most Ceroptres
  • single host gall species or related galls - associated with phylogenetically or ecologically related

Behavior

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

Ecological Role

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