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.

The Prismatic Lacewing can be caught with a Bug Net. Releasing it from the inventory (with ) in any Hallow biome 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.
 * The spawn rate is increased in Hallow biomes in the outer 1/3 of the world.
 * 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.
 * Lacewings seem to only spawn in Hallowed Forest biomes and Hallowed Desert biomes. They can rarely spawn in Hallowed Snow biome. 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. and then eat cheese and enjoy it
