Infested Firefly

A Infested Firefly is a Pre-hardmode Critter style monster that spawns in the Infestation. Its main purpose is unlocked in hardmode, but it is always a good idea to stock up on these at night, as they have a 30% bait power. These bugs are used in Ascension. If you ascend 500 of these critters, you will be granted the Infest Mental Spell.
