dead and cream colored

 

It is soft and fibrous due to the presence of white

    wood-rotting fungus which degrades cellulose,

    hemicellulose, and lignin. 

 

Active nests were found in trunks that were not

    cracked and did not have other invertebrate

    organisms living within 20 cm of the entrance to the

    nest.

 

Abandoned nests had cracks and tunnels that were

    lined with fungal hyphae, or had evidence of

    invaders (wasps, ants, spiders, or other bees).

 

Banksia nests could last for several years.
