A Butterfly / Flower Farm is formed by catching lots of Butterflies and planting them as Flowers in a small space. Flowers will spawn more Butterflies. Alternatively, the player can catch a bee with a Bug Net, then drop it on the ground. "Homeless" bees will wander and spawn flowers at random instead of returning to a hive/box.
They are advisable alternative healing method to the flower petals, as they are 8 times more effective. Additionally, they may be used in the Crock Pot recipe Butter Muffins.
An efficient way to hunt Butterflies is to run close to them while they are moving (or not) and to do a quick attack by pressing Ctrl+F with no weapon.
Pigs that eat butterfly wings will produce manure, just like when they eat a vegetable. However a pig cannot be given the wings directly - the player must drop the wings on the ground and wait for the pig to walk over and eat it himself.
