Brutalfly

 Brutalflies are strong Boss Mobs that are effectively weaker Mothras that behave in a very similar manner.

They spawn if a Caterkiller is given enough time to become one.

Summary
Brutalflies can shoot fireballs at fast speeds, but only shoot the small ones compared to Mothra, who can shoot large explosive ones. The small ones will cause small Fires.

When they die, they will explode into a variety of Butterflies.

How to Kill
A very effective strategy is using a Bow with reasonable Enchantments. A Emerald Sword or a Amethyst Sword is also effective for the player.

The player can also bring armor with Fire Protection or a Potion of Fire Resistance if they are unsure of their dodging skills.
