Hallow nocturnal glow and net harvesting
The Lightning Bug takes flight above the surface Hallow between dusk and dawn, illuminating the landscape with an energetic cyan radiance. Players capture them using any Bug Net as they flutter in swarms over pearlstone and pastel grasses. Combining one with a Bottle creates a Lightning Bug in a Bottle, an alternative light fixture that can be suspended from ceilings for home decoration.
Hardmode insect power and angling performance
Carrying 35% bait power, this glowing insect acts as the Hardmode evolution of the pre-Hardmode Firefly, which offers only 20% bait. Its elevated rating substantially improves quest fish bite rates while reducing bait depletion when casting into oceans or underground lakes. Harvesting swarms during new moon cycles builds an enduring supply of dependable bait for late-game fishing expeditions without spending coins.
Trivia
- Lightning bug spawns spike dramatically when new moons coincide with calm surface weather.
- The bottled decorative variant emits slightly brighter luminescence than bottled yellow fireflies.
