 Reproductive success is strongly affected by insects that infest the flower spikes and fruiting structures . Infestation of the flower spikes is not as severe as in other Banksia species : one study found less than 10 % of B. telmatiaea inflorescences to be infested , compared to over 50 % for B. attenuata ( Candlestick Banksia ) , B. littoralis and B. menziesii ( Menzies ' Banksia ) , and over 90 % for B. grandis ( Bull Banksia ) . Also , whereas other species were attacked by a range of insects , the inflorescence of B. telmatiaea was attacked only by the <unk> moth Arotrophora <unk> ( Banksia Boring Moth ) , which burrows into the woody axis , rendering the spike barren . On the other hand , the same study observed heavy infestation of fruiting structures , with over 90 % of spikes with follicles found to contain at least one larva of an unidentified species of moth of the genus Xylorycta . These larvae burrow from follicle to follicle to eat the seed , resulting in 100 % seed loss for infested spikes .
