{{further|Gall|Gall wasp}}

Many [[galls]] are found on oak leaves, buds, flowers, and roots. Examples are [[oak artichoke gall]], [[oak marble gall]], [[oak apple]] gall, [[knopper gall]], and [[Neurotus quercus-baccarum|spangle gall]]. These galls are the handiwork of tiny wasps from the  [[Cynipidae]]. In a complex ecological relationship, these gall wasps become hosts to [[parasitoid wasp]]s—primarily from the order [[Chalcidoidea]]—which lay their larvae inside the gall wasps, ultimately leading to the hosts' demise. Additionally, [[inquiline]]s live [[Commensalism|commensally]] within the galls without harming the gall wasps.<ref>{{cite journal |last1=Askew |first1=Richard R. |last2=Melika |first2=George |last3=Pujade-Villar |first3=Juli |last4=Schönrogge |first4=Karsten |last5=Stone |first5=Graham N. |last6=Nieves-Aldrey |first6=Jose Luis |title=Catalogue of parasitoids and inquilines in cynipid oak galls in the West Palaearctic |journal=Zootaxa |date=30 April 2013 |volume=3643 |issue=3643 |pages=1–133 |doi=10.11646/zootaxa.3643.1.1 |pmid=25340198 |isbn=978-1-77557-147-6 |url=https://www.researchgate.net/publication/237007745}}</ref>
