Watch Australian bees create a detailed spiral nest.

Bees are not just builders—they're also artists. Nest designs vary across species, with one Australian bee recently gaining attention for its remarkable, spiral-shaped structure.

According to Live Science, the Australian stingless bee Tetragonula carbonaria sparked the curiosity of Reddit users when an image of its extraordinary brood nests, a unique spiral design for breeding, was shared earlier this month.

Brood nests are multi-tiered, and the image reveals just one of their numerous layers. Experts explain that fully mature brood nests can feature between 10 to 20 circular segments, each containing hundreds of individual egg chambers. The eggs transform from larvae to pupae to adult bees, and when the mature bees leave their cells, the remaining ones continue adding to the nest by creating more brood cells.

Experts remain uncertain about why Tetragonula carbonaria constructs spiral nests. Some researchers believe the spirals might be a space-saving design that also allows for better air circulation. While the mystery remains unsolved, you can witness Australia’s stingless bees at work by watching the video below.
