Queen Bee is a pre-Hardmode boss. She is summoned by breaking the Larva inside Bee Hives of the Underground Jungle, or by using an Abeemination anywhere within the Jungle. She can inflict the Poisoned debuff. Queen Bee has three distinct attack patterns:
She will level herself horizontally with the player and fly back and forth three times in an attempt to ram the player.
She will spawn Bees while hovering (which will include larger ones in Expert mode), which attack the player.
