Prismatic Lacewing

The Prismatic Lacewing is a rare flying Critter that spawns in the Surface Hallow from dusk until midnight after Plantera has been defeated. When killed by a player, it summons the Empress of Light; death from non-player sources other than Fallen Stars will not result in summoning.

The Prismatic Lacewing can be caught with a Bug Net. Releasing it from the inventory (with ) in any biome (even if it will quickly disappear outside of the Hallow) and then killing it will still summon the Empress of Light. Only one Lacewing can be naturally spawned at a time. Because it can only spawn between dusk and midnight, its spawn is limited to between the times of 7:30PM and 12:00AM. This can also be used to craft a Prismatic Lacewing Jar.

It is one of the few critters that can be detected by the Lifeform Analyzer.

Tips

 * The Guide To Critter Companionship can be helpful to prevent accidentally summoning the Empress of Light.
 * A Lifeform Analyzer can be used to see if a Lacewing is nearby.
 * Using a Battle Potion and Water Candle increases its spawn rate, like other monsters.
 * Similarly, because it is considered an enemy, its spawn rate is increased during the Blood Moon event and can be easily farmed using a Bloody Tear.
 * Building a platform roughly 35 tiles above a Hallow biome while under the influence of a Water Candle, you can expect 3-8 Lacewings to spawn, provided you are there from 7:30PM to 12:00AM.
 * If you do not have a surface Hallowed biome in your world, you can use a Clentaminator with Blue Solution to create one.
