How to Find Fireflies and Firefly Bushes in Minecraft

As of Minecraft snapshot 25w05a, fireflies appear at night through firefly bush blocks. They add a small glow, help stop nearby mob spawning, and make swamps feel slightly less suspicious.

Minecraft Fireflies Are Particles, Not Mobs

Minecraft fireflies are not separate mobs like bees or frogs. They are glowing particles that appear around a block called the firefly bush.

During the day, firefly bushes resemble regular bushes, but with a darker green base, yellow-tinted leaf tips, and glowing firefly pixels. At night, fireflies float around the surrounding area.

Where to Find Firefly Bush Blocks

To find Minecraft fireflies, search for firefly bush blocks. As of Minecraft snapshot 25w05a, also referred to as Minecraft 1.21.5, these blocks generate in swamp biomes and along rivers.

Rivers are common while exploring, and swamps can appear after some Overworld travel. Checking riverbanks is often the quickest first step before hunting for a full swamp biome.

Once found, a firefly bush can be collected by hand, placed elsewhere, and duplicated with bone meal. It produces a light level of two, preventing mobs from spawning in a very small radius.

Finding Swamps with Commands

If exploration fails, the `/locate` command can point to a swamp biome. It returns the nearest coordinates and may allow teleporting if permissions support it.

The command is:

• /locate biome minecraft:swamp

Locate biome commands require cheats in singleplayer and OP permissions on multiplayer servers.
