Assassin Bug

Assassin bugs are insects that will kill other insects (earning them their name) and suck their food up like juice, literally. This would be pretty good to use because you can use them. If you lure them in a stronghold or mineshaft with a bee they will kill any silverfish, endermites and other arthropods in the game. They will put wither or poison on enemies. They will be the size of silverfish and will be red. They spawn naturally in meadows and wait near flowers for a bee to come. This makes them slightly annoying but they are more useful then annoying. They have 20 health and are neutral to players. They are hostile to arthropods but if it attacks an  evil arthropod it makes other monsters try to go after it giving it more enemies. These are useful mobs for mob farms because of this. You could transform a whole mineshaft into a mob farm because of these! They will breed themselves. When killed they drop 4 experience points but no item. Now here are some details. If you got spawn eggs that summon arthropods with commands or in creative mode and it kills you it will "eat" the spawn eggs. If they are seen by bees the bee gets scared and flies away. If you break the flower one is waiting by it will leave and go to a nearby flower. Write ideas in comments.
