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.[1] 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.

The long version of a beehive could be seen as the pond or the loaf, and the long long version the mango. The beehive could also be thought of as a long tub. Further extension is however not possible, making this a closed family of primitive still lifes. However, the beehive, loaf and mango admit a process of replacing the singleton edge cells with four "feet" cells: in the case of the beehive, this yields hat and table on table.

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.
