Queen Bee

Info
Queen Bee is the third hardest Pre-Hardmode boss in Terraria. She takes the form of a huge queen bee, with multiple holes on her rear that shoot out bees. She drops items that are incredibly useful when fighting The Wall Of Flesh.

The Queen Bee will attack the player by chain ramming them. She can surpass through blocks, so when will usually exit the player's screen before returning for another ram. Eventually, she will switch to her bee attack, where she will hover above the player while spewing out bees from her rear. These bees inflict the poisoned debuff on the player when they attack you. The lower Queen Bee's health gets, the faster and more often she will ram the player.

In order to summon Queen Bee, you must either break a Larva inside of a hive in the jungle, or use the Abeemination ( 5 Honey Block +Stinger + 5 Hive block + Bottled Honey no external crafting item required). The Larva(e) inside of the jungle hives is incredibly fragile, and will break if you do anything other than completely leave it alone. In order to provide complete safety from The Larva breaking, surround it in blocks (make sure not to place any on it, as this will break the Larva).

Strategies

 * If possible, always have a nearby house with a nurse and a dryad living there. The nurse can completely refill your health for a few silver coins, and the Dryad generates the 'Dryad's Blessing' debuff which increases your defence. She also generates the Dryad's Bane debuff that negatively effects enemies. Also, make a long, flat arena, with heart lanterns, Campfires and Fireflies/Stars In Bottles. For this particular area, using honey pools is recommended since you are directly next to one in a hive.
 * When fighting Queen be, use weapons that inflict the On Fire! or Poisoned debuff, as she is vulnerable to them. Fiery Greatsword, Imp Staff, Flaming Arrow and Flare are all examples of On Fire! Inflicting Pre-Hardmode weapons. Blade Of Grass, Thorn Chakram and Poisoned Knife are all examples of Poisoned inflicting Pre-Hardmode weapons.
 * Melee Weapons are recommended, as Queen Bee stays out of range for a great portion of the Bossfight. If you do use ranged weapons, make sure they are high in damage and/or inflict Poisoned or On Fire!.
 * Fighting Queen Bee above ground is recommended, since underground you have limited space, and it takes longer to renovate an arena. For the same reason, and Abeemination is more useful than smashing a Larva. If you do choose to smash a Larva, make sure you have a quick exit to the surface.
 * Using Rocket, Lightning or Spectre Boots is highly recommended as Queen Bee is incredibly fast.
