The Prismatic Lacewing is a rare flying critter that spawns in the surface Hallow from dusk (7:30 PM) until midnight (12:00 AM) 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 ⚒ Use / Attack) and killing it will still summon the Empress of Light (though it will quickly disappear if released outside of the Hallow). Only one Lacewing can be naturally spawned at a time. It can also be used to craft a Prismatic Lacewing Jar.

It is one of the few entities that can be detected by the Lifeform Analyzer or its upgrades.

Lastly, it only starts to spawn after the boss Plantera has been defeated in your current world. So, if you're having trouble finding this elusive critter, make sure all these conditions are met!

What conditions are required for the Prismatic Lacewing to spawn?

The Prismatic Lacewing, a rare flying critter in Terraria, spawns under specific conditions. It appears in the surface Hallow biome from dusk (7:30 PM) until midnight. However, this only happens after the boss Plantera has been defeated in the current world.

Notes

• The Lacewing is classified in-game as an enemy so others won't kill it and spawn the boss by accident. However, player summons will not actively target it, though they might kill it via contact damage and unintended attacks.
• The Lacewing will despawn almost immediately if released outside the Hallow, but can still be killed to summon the Empress of Light if done fast enough or if placed directly onto a damaging projectile, like that of the Rainbow Gun.
• Lacewings will only spawn on Hallowed grass (not including its mowed variant), Pearlstone Blocks, Pearlsand Blocks, and Pink Ice Blocks.
• A Lacewing can only be damaged by a player if they are close enough and will appear translucent if the player is far away. This is likely done to prevent accidentally summoning the Empress of Light via a stray ranged attack while the Lacewing is off-screen.
• If killed by bees or traps, the Empress of Light does not spawn, unless the player also struck it at least once.
• Unlike other critters, the Lacewing does not regenerate life.

Tips

• Using a Bug Net, it can be kept in the player's inventory to later release it at a more appropriate time, such as to fight the Empress of Light when better prepared.
• 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, the player can expect 3-8 Lacewings to spawn, provided they are there from 7:30 PM to 12:00 AM.
• If the player does not have a surface Hallowed biome in their world, a Clentaminator with Blue Solution can be used to create one.
