A field study carried out at Jandakot Airport south of Perth and published in 1988 found that birds and insects overwhelmingly preferred visiting yellow-coloured flowerheads. The species recorded include several species of honeyeater, including the red wattlebird ("Anthochaera carunculata"), western wattlebird ("A. lunulata"), western spinebill, brown honeyeater ("Lichmera indistincta"), New Holland honeyeater ("Phylidonyris novaehollandiae"), white-cheeked honeyeater ("P. nigra"), singing honeyeater, ("Lichenostomus virescens"), as well as the twenty-eight parrot ("Barnardius zonarius semitorquatus") two species of native bee of the genus "Leioproctus", a beetle of the genus "Liparetrus", and ant species "Iridomyrmex conifer". The yellow flowerheads are also the ones that bear the most nectar, and are greatly preferred by red wattlebirds.
