Similar to the [[snacker]], the worker bee is extensible - it is, in fact, a finite version of the infinite [[one-cell-thick pattern|one-cell-thick]] oscillator consisting of alternating groups of six ON cells and two OFF cells.

Worker bee (or lonely bee[1]) is a period-9 oscillator and was found by David Buckingham in 1972.[2][3] It consists of four eater 1s hassling a line-of-six spark.

Similar to the snacker, the worker bee is extensible - it is, in fact, a finite version of the infinite one-cell-thick oscillator consisting of alternating groups of six ON cells and two OFF cells.

This oscillator first appeared semi-naturally in April 2015, in a symmetric soup submitted to Catagolue by Dave Greene.[4]

p6 worker bee

The same unstable object (albeit not in the one-cell-thick phase) is also hasslable by four toads to form the p6 worker bee or by an unnamed object, mutually stabilising each other, to form an unnamed fourfold variant.

In other rules

In other Life-like rules with transition S8, for instance EightLife, the core of worker bee evolves into a honeycomb, making the still life more common than that in regular Life.

By removing the isotropic non-totalistic transition B3r, the worker bee needs no external support. A row of 6 cells becomes a small period-9 pipsquirter.
