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. Killing it summons the Empress of Light boss; death from other causes will not result in summoning.

The Prismatic Lacewing can be caught with a Bug Net. Releasing it from the inventory (with ) in the hollow 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 in preventing one from accidentally summoning the Empress of Light.
 * A Lifeform Analyzer can be used to see if one is nearby.
 * Using a Battle Potion and Water Candle increases its spawn rate, like other monsters.
 * Similarly, because it is considered an enemy, the 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 don't have a Hallowed Forest or Desert in your world, then you can use a Clentaminator with Blue Solution to create one.
