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 blocks, but are rarer than Fireflies. All naturally spawned Lightning Bugs can be caught with the Bug Net, Lavaproof Bug Net or, 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, 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, or sold to any NPC vendor for.

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 (both  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 firefly, not a distinct insect.
