 Pollinators of B. epica include Phylidonyris novaehollandiae (New Holland honeyeater) and Acanthiza chrysorrhoa (yellow-rumped thornbill). No other pollinators have been recorded, but the species is poorly surveyed, and studies of other Banksia species have consistently indicated a wide range of invertebrate and vertebrate pollinators. For example, a survey of the closely related and co-occurring B. media found that "honeyeater birds and marsupial nectarivores were abundant in the study area and most carried the pollen of Banksia media while it flowered. … Self-pollination and pollination by insects clearly also play major roles in seed production."
