Queen bee is a pattern that lays two beehives before exploding. Because of the way in which it lays those beehives, it is simple to stabilize into an oscillator, as in the well-known queen bee shuttle. The term queen bee refers not just to the phase shown to the right, but also to any of the other phases of the pattern (excluding the beehives it creates) that occur before it explodes.

Turning reaction

One of the simplest reactions involves a queen bee involves colliding it with two gliders that come in from opposite directions in order to turn (reflect) it; this reaction was found by David Bell and was turned into a period 88 oscillator (shown below) on March 21, 1996. The reaction itself turns the queen bee counterclockwise by 90 degrees in 22 generations.[1]
