Mesostigmata
Mesostigmata is a diverse group of predatory mites belonging to the subclass Acari. They are characterized by having a specialized feeding structure called a hypostome, which is used to pierce and suck the fluids from their prey. These mites play a crucial role in controlling pest populations in various ecosystems and are important in maintaining ecological balance. Mesostigmata can be found in a wide range of habitats, from soil and leaf litter to animal nests and bird feathers. They are known for their fast movement and aggressive predatory behavior, making them effective predators of other small invertebrates.
