Worker bee (or lonely bee[1]) is a period-9 oscillator and was found by David Buckingham in 1972. Unlike the similar snacker, the worker bee produces no accessible sparks (note the generated monominos), and is thus not considered to be very important. Like the snacker, the worker bee is extensible - it is, in fact, a finite version of the infinite oscillator which consists of six on cells and two off cells alternating along a line.
This oscillator first appeared semi-naturally in April 2015, in a symmetric soup submitted to Catagolue by Dave Greene.[2]
