“Uit de analyse (studie Kennedy & Southwood 1984) kwamen wilgen en inheemse eiken naar voren als meest soortenrijke boomsoorten, met per genus respectievelijk 450 en 423 fytofage insectensoorten. De oefening werd later nog eens overgedaan in Duitsland (Brändle & Brandl 2001). Op het Europese vasteland liggen de soorten nog hoger, maar blijft de ranking van de boomsoorten nagenoeg hetzelfde: 728 soorten voor wilg Salix sp. En 699 soorten voor eik Qercus sp.”
