Batflies are passive, flying, insectoid creatures that act as one of Slugcat's primary food sources. They are one of the most common creatures in the game, appearing in almost every region.
Batflies are small black insects with two wings, antennae, and white eyes. They have no variation.
Batflies can be caught and eaten to fill 1 food pip. Batflies are wary of Slugcat, but are usually slow in their evasion. They can be caught easily by jumping towards them and grabbing. Catching Batflies may be easier from above, as they often stop and hover in place. Jumping from above also makes it easier to catch Batflies through use of the game's Batfly auto-grab feature. Rocks and Spears can also be used to kill Batflies from afar. Batnip attracts Batflies, which makes them easier to catch. Unlike other food sources, Batflies do not persist in shelters, and are either auto-consumed or deleted.
Batflies can be used to distract certain creatures, such as Pole Plants and Monster Kelp. When thrown in range, these threats may prioritize the Batfly over Slugcat, retreating into their dens to consume them. Batflies can also be used to distract Jetfish and raise reputation with Squidcada.
Batfly Spear Linking, also known as Batspearing, was a glitch in pre-1.9 versions of Rain World. In 1.9, enabling Remix corrects the glitch, unless "Vanilla exploits" is enabled in its options.
When a Spear is thrown through a Batfly that has already been impaled on another Spear, the game behaves as though it is impaled on both. The Batfly may appear to get transferred to the new Spear, but this is not necessary for the glitch to apply. When one Spear exits a room, enters a transition pipe, or enters a den, the other forcibly warps with it, including anything that the Spear is currently embedded in. This can be used to transport large creatures. The game can become softlocked if a creature retreats to its den while Slugcat is holding a linked Spear, however.
This glitch is significantly easier to perform as Hunter due to their back slot: if the Spear on the back has an impaled Batfly, any thrown Spear pierces through it. Any amount of Spears can be linked at once. Linked Spears that have been embedded into walls also warp, but can not be climbed on once they move rooms. Removing the Batfly from the linked Spears stops the glitch.

Batflies can be found in 'hives' around the world, known in-code as swarm rooms. These rooms feature black, white-tipped plants. Every cycle, Batflies attempt to migrate to a new swarm room. Depending on how many Batflies Slugcat has killed, multiple Batfly hives may be empty. When a hive is empty, the plants lose their white tips. Active Batfly hives are indicated on the map by pulsing blue rings.

The white-tipped plants that Batflies nest in also act as Batfly-exclusive travel pipes. When a threat gets too close to a Batfly, they may dive and burrow into these plants. After a few seconds, they re-emerge from a different plant elsewhere in the room. Batflies can still be grabbed while in their burrowing animation.
Batflies can hang upside down from ceilings, poles, and even each other, forming stacks. If a Batfly with others attached to it from below starts flying, the attached Batflies may not separate, and they can end up struggling to fly. If Slugcat grabs a Batfly attached to a chain, the entire chain is picked up until the other Batflies fly away. This can result in strange physics if the Batflies are still attached to the ceiling.
