Features
Butterflies
Butterflies are small creatures that fly around the world. Right-click on a butterfly to capture it, and drop it on the ground to release it again! Butterflies can be used to cross-pollinate Forestry trees. They also support the full Forestry: CE genetics system, meaning they can be bred to discover new species and to choose certain traits, such as size, pollination speed, and more!
Butterflies normally drop nothing when killed, but if they are carrying Tree Pollen, they will drop it upon death.
Serum
A Butterfly Serum is obtained by completing the Escritoire minigame while studying a Butterfly. It can be placed in a crafting grid with a butterfly to obtain a Mated Butterfly, the first step in the Butterfly breeding process!
Caterpillar
A Caterpillar is occasionally spawned when a Mated Butterfly settles onto Forestry Tree Leaves. The Caterpillar can be retrieved by right-clicking the leaves with a Scoop!
Cocoon
Over time, a Caterpillar will start to build a Cocoon hanging from below its Leaves block. This Cocoon matures over time until it hatches into a new Butterfly!
