Two Insects aka Two More Insects aka TwoInsects aka Brood Maidens & Giant Flies
Brood Maidens (Boss Mob)
The Brood Maiden is a half-human half-spider half-naked boss monster that periodically spawns spiders and giant flies. This mob can only be encountered at night, and you will never see more than one in the same place. She's incredibly depressed about the job she has to do, but her minions cling to her like loving children and will tear apart anything she looks at. She never actually attacks anything herself, but the spiders and flies get the job done just fine by themselves. As they continue to roam the surface of the world, they will continuously pick targets. Any living creature other than herself, her minions, or other monsters can become a target. And that, of course, includes you.
If you damage the Brood Maiden or she happens to pick you as a target, you'll soon find yourself in the company of several angry insects. The Brood Maiden is able to spawn two minions at a time, and the maximum amount of followers she can have at once is five, or two when there isn't a player nearby. Every ten seconds or so, she releases two more bugs who immediately chase after her current target. As you damage her, she will scream at you, and more damage makes her release minions faster. But even though her "life" is such a tragedy and you want to kill her so badly - That's not the point.
The Brood Maiden is being controlled by an artifact - that crown on her head. With the cursed silver frame and the powerful purple jewel, Beelzebub controls her every action from the shadows, and can easily call her back to the Nether if things get rough. What happens when you kill her? You get a crummy little bit of string. So take my advice and do the following: keep hitting her until her HP reaches a critical state - 1 to 9 percent. She has 100 HP, so this may take a while. Once she has reached this state, she will transform into her powerless human form. As soon as this happens, right-click her as fast as you can. She will die in one hit at this stage and she'll barely last two seconds before she vanishes, so be quick. Even her followers will turn on her when they see her human form! If you are successful, you will remove the jewel from her crown, and her soul will be freed of the demon's control. You can then breathe a sigh of relief knowing you've done a good deed, and watch her free spirit float up into the sky. But what are the jewels good for?
Well, I'm glad you asked. The jewel of the crown acts as a power supply, so it contains a large amount of magic which can be harnessed by the player. 
Can be used in crafting to form a new special sword for you to use. The sword is called a Shock Blade, named after its ability to do shock damage to enemies. It has the strength and durability of an iron sword, but all living creatures around the enemy you strike (3.5 block radius) will recieve a small amount of damage as well. This applies to all enemies, making it amazingly useful for taking out large crowds. The downside? Any living creature can get caught within its effect. This includes friendly mobs like mounts, pets and companions, so be careful.

*Hates absolutely everything and complains too much
*Fun, but very difficult to fight
Giant Flies (Docile Mob)
While the Brood Maiden uses them for evil purposes, they are more-or-less harmless by nature. Spawning in small groups like all animals, they will hover around the surface during the daytime and occasionally snack on an animal that passes by. Flies only need to feed once every minute, and only attack for 2HP of damage, so realistically, it will take five minutes for a fly to kill one pig.
They won't attack humans either, unless provoked. Even then, they will still only attack once before they fly away and forget about it. Only Brood Maidens are able to make the flies act aggressively, so as long as there isn't one nearby, flies are safe to be around. Flies have 10 HP and are easy to defeat. They can either drop leather (from their tough hides), or flint (chipped off of their hard stomach plating). Like spiders, their red eyes glow at night.
Info and Advice:
*Has 10 HP
*Does not attack the player unless provoked or near a BM
*Occasionally attacks animals when hungry
*May hover or walk around the landscape
*Drops leather or flint
*Fairly large hitbox
*Easy to kill for the most part
*Makes annoying noises
