What it does

Moths and butterflies appear in the world as passive mobs. The Silk Moth gathers in dark spaces and produces silk, and it can grow from a Silk Worm once monsters spawn nearby. Three butterflies follow the same pattern: the Chilly Butterfly, the Sizzling Butterfly and the Eclipse Butterfly, each tied to a different light level or biome and each breeding with flowers.

Each butterfly has a chance to affect anything that attacks it. The Chilly Butterfly can freeze an attacker, the Sizzling Butterfly can set it on fire, and the Eclipse Butterfly can wither it. Bright spaces yield snowballs or fire charges from the first two, and the nether yields nether wart from the Eclipse Butterfly. The mod is a world generation mod for Fabric and is installed on the client and the server, so both sides need it.

The mod is published for Fabric only, across four game versions: 1.21.8, 1.21.9, 1.21.10 and 1.21.11. It is not open source, and all rights are reserved by the author.
