One field study found 30% of seeds were eaten by insects between bushfires. Insects recovered from inflorescences include the banksia boring moth ("Arotrophora arcuatalis"), younger instars of which eat flower and bract parts before tunneling into the woody axis of the spike as they get older and boring into follicles and eating seeds. Other seed predators include unidentified species of moth of the genera "Cryptophasa" and "Xylorycta", as well as "Scieropepla rimata", "Chalarotona intabescens" and "Chalarotona melipnoa" and an unidentified weevil species. The fungal species "Asterina systema-solare", "Episphaerella banksiae" and "Lincostromea banksiae" have been recorded on the leaves.
