Alien LarvaHardmode exclusive
The Alien Larva is a Hardmode, post-Lunatic Cultist enemy which appears around the Vortex Pillar during the Lunar Events. They move fairly slow along the ground. A number of these spawn on the death of an Alien Queen. If unattended, they will grow into Alien Hornets, which in turn become Alien Queens later on.
- The Bestiary entry for the Alien Larva: "The larval stage of the alien hornets. They may seem weak and harmless, but if ignored they will evolve into powerful beings."
