[11] Because of the large trunk size some trees develop, people have assumed that individual H. macrocarpa trees may be up to 2,000 years old.
The worker bees in the colony mix dry pollen with nectar and/or honey with their enzymes, and naturally occurring yeast from the air.

Pollen of T. populnea viewed under a light microscope. The Portia tree reaches a height of 6–10 m (20–33 ft) tall and its trunk can measure up to 20–30 cm (7.9–11.8 in) in diameter. [20] It grows at elevations from sea level to 275 m (902 ft) [21] in areas that receive 500–1,600 mm (20–63 in) of annual rainfall. [10]
