Mushi Ladybug

The Mushi Ladybug is a monster that spawns in mushroom biomes, both above and belowground. They are capable of short-distance flight, and are very tough for pre-hardmode enemies. Due to their high damage, they are very good at killing unsuspecting players.

Trivia

 * Part of the Mushi Ladybug's name, specifically "Mushi", means "insect" in Japanese. (This probably isn't a coincidence.)
