Lawrence's Ambient Fireflies
by Lawrence360
Lawrence's Ambient Fireflies is a world generation datapack that places fireflies as ambient particles in swamp and mangrove swamp biomes.
What it does
Installed in a world's datapacks folder, the pack adds firefly particles to swamp and mangrove swamp biomes, with no new items or blocks. Because it is a datapack, it works on Fabric, Forge, NeoForge and Quilt alike, and server owners only need to place it in the world. It is server required, and clients may add it as well. The author notes it should combine with most other datapacks, but it does not directly change swamps and mangrove swamps in a way other mods can rely on. Builds exist for 26.2, released under the MIT License, and are not open source.
Key features
Swamp ambient fireflies
Fireflies appear as ambient particles in swamp biomes, adding life to marshland at dusk.
Mangrove swamp coverage
The same firefly particles also appear in mangrove swamp biomes, so both swamp types are covered.
Lightweight datapack
The pack is small and adds no items, blocks or mod code, so it installs by copying it into the world.

What the author says
A small and very lightweight pack that adds fireflies as ambient particles to the Swamp and Mangrove biomes. It'll work with most other datapacks? It for sure won't work with any other mods/datapacks that directly change swamps/mangrove swamps directly so just keep that in mind.
