Firefly

Spawning

Fireflies spawn at night in groups of 2-3 in various biomes, including plains and forests.

Drops

Fireflies drop upon death:

• 1–3 experience orbs if killed by a player or tamed wolf.
• 0-1 glow goop. The maximum is increased by one per level of Looting, for a maximum of 0-4 with Looting III.

Item drops can be edited with a data pack via editing loot_tables/entities/firefly.json in Naturalist’s data files.

Behavior

Fireflies aimlessly fly around, flickering the glow of their behind on and off in somewhat random intervals.

When it becomes daylight and a Firefly is not nametagged or persistent via something like being put in a Boat, they will go into the grass, spawning grass breaking particles and a small shuffling noise before despawning.
