Beehive is a 6-cell still life. It is the second most common still life, being less common than block but over three times as common as loaf. Beehives are frequently born in a set of four called honey farm, and a lone beehive can be turned into one by adding a corner (turning it into a bun), adding a cell to the "tip" of it (the bit with one cell, adding it to the longer end will result in a R-pentomino predecessor) or by adding one cell inside it. There are also formations of two beehives that also occur fairly commonly, evolving from seeds known as butterfly and teardrop.
A beehive can be eaten with a block, a reaction that allows the construction of the queen bee shuttle and further patterns based on it.
