Although native bees generally seem to have been sparse here this season, suddenly the bee condominium has become a hive of activity to coin a phrase. Resin bees have been working busily provisioning and sealing their brood chambers. The seal is made from resin and chewed leaf, both obtained from the Eucalyptus leucoxylon not far away. The source of the pollen is unknown but flowering grevilleas, correas, eremophila and vanilla lilies are possibles. The first images show one bee making the final seal.
Here is the seal completed.
A short distance away in the condo another bee is also working, the first picture shows it with its abdominal hairs loaded with pollen.
Later pictures showed it going in without pollen, perhaps with resin.
