Not to be confused with Etherian Lightning Bug.

Lightning Bugs are harmless critters that can be caught with a Bug Net and do not normally interact with the player in any other way, except in that they can be killed by both players and enemies. They have 5 health and usually serve as ambient entities in Terraria.

Lightning Bugs spawn during the night above Hallowed grass with wind speeds under 20 mph in any direction, it spawns more frequently during a New Moon. All naturally spawned Lightning Bugs can be caught with the Bug Net, Lavaproof Bug Net, or Golden Bug Net, and carried in the player's inventory (or placed in storage). If a Lightning Bug caught with any Bug Net is taken from inventory and "used" (placed), it is again released into the environment at the cursor and behaves as usual. On  PC,  Console,  Mobile,  tModLoader, and  tModLoader Legacy, critters spawned from statues cannot be caught with the Bug Net; attempting to do so will cause the critter to disappear in a puff of smoke.

A caught Lightning Bug can be crafted into a Lightning Bug in a Bottle to create animated display furniture. Once crafted, the critter cannot be released. They can furthermore be used for fishing, with a bait power of 35%, or sold to any NPC vendor for 5.

Notes

• The spawn rate of Lightning Bugs is randomly determined upon dusk. Therefore, there will be massive swarms on some nights and on other nights very few will spawn.
• Lightning Bugs as well as Fireflies spawn at a higher rate on nights during a New Moon.
• They may spawn in huge amounts if the two factors above (correct moon phase and high random daily spawn rate) coincide. Hundreds of them can then be farmed in the time of a night this way.

Tips

• Similar to Fireflies, they are very useful as bait due to the large quantities that can be obtained per night. Note that they only spawn in The Hallow, which makes them Hardmode-exclusive.

Trivia

• Although it may seem as if the Lightning Bug is the "Firefly version" of the Enchanted Nightcrawler (both 35% bait power with similar color changes), it is not crafted, contrary to the Enchanted Nightcrawler.
• In real life, lightning bug is just another name for a firefly, not a distinct insect.

The Bestiary entry for the Lightning Bug: "Appears at night in blessed locations, filling the sky with flashing cyan light. Fish are especially attracted to these."
