Humidity and new mob "culicids"

The idea of ​​this would be to add a new bar in the f3 which would measure the humidity of the biome and at night in the most humid biomes that the culicids appear which would normally appear in the mangrove biome and can be eliminated by entering the water or with a object you rub on the armor that scares them. It would be nice if they added it to the game because since the mangrove biome was added I felt it a bit empty, obviously there are frogs but it would be good food for them and also a difficulty for the player.
