Beetles

Beetles are rare enemies that can be found in different biomes.

There are three types of beetle: The Cochineal Beetle that spawns in the Cavern layer, the Cyan Beetle that spawns in the Ice biome and the Lac Beetle that spawns in the Underground Jungle biome. They respectively drop the Red Husk, the Cyan Husk and the Violet Husk which can be used to respectively make the Red Dye, the Cyan Dye, and Violet Dye.

They are all immune to the Confused debuff.

Trivia

 * The Cochineal Beetle and the Lac Beetle exists in real life, but they are a scale insect, not a beetle. It secretes lac, which can be used as dye or converted into shellac, a brush-on colorant, food glaze and wood finish.
