Forestry: CE - Butterflies

by thedarkcolour

Forestry: CE - Butterflies adds butterflies, moths and caterpillars to the Forestry insect system, and it is a NeoForge mod for 1.21.1.

NeoForgeClient and serverGNU Lesser General Public License v3.0 onlyOpen source1.21.1

What it does

Players catch butterflies and moths, breed them, and collect 35 different species. A butterfly that is killed normally drops nothing, though it carries Tree Pollen that drops upon death. Butterfly Serum comes from completing the Escritoire minigame for studying a butterfly, and a placed crafting grid holding a butterfly yields a Mated Butterfly, the first step in breeding.

Caterpillars appear now and then when a Mated Butterfly settles on Forestry Tree Leaves. Right-clicking a leaf block with a Scoop lets a player pick up a caterpillar from it. Over time the caterpillar builds a cocoon that hangs below the leaves block, and the cocoon matures until it hatches a new butterfly. The mod is the last original Forestry feature to be added, and it requires Forestry. Client and server both need it, and the mod is open source under the GNU Lesser General Public License v3.0 only.

Key features

  1. Catching butterflies and moths

    Butterflies and moths can be caught and kept, which opens the breeding system.

  2. Thirty-five species

  3. Tree Pollen drops

    Killed butterflies usually leave nothing, but they drop Tree Pollen upon death.

  4. Caterpillars and cocoons

Questions

Does Forestry: CE - Butterflies need Forestry?

Yes. The mod requires Forestry to run, so Forestry must be installed alongside it.

Does the server need the mod?

Yes. Servers that run it need every player to install it too.

How does a player get a Mated Butterfly?

A butterfly is placed into a crafting grid, which yields a Mated Butterfly as the first step of breeding.
