Dust Mite

Mites are the most numerous group of arachnids *(Arachnida)*. Their bodies are only indistinctly segmented, and some of their internal systems, such as the circulatory and respiratory systems, are reduced. However, their chelicerae have undergone significant diversification, enabling mites to exploit a wider range of food sources than any other arachnid group. Mites can be found virtually everywhere, and their varied diets reflect this diversity. Some are predators of other invertebrates, while others are parasites, even on aquatic animals. This group also includes ticks, which are known for their role in transmitting serious diseases from animals to humans. Many mite species are agricultural pests, commonly found in food storage areas, granaries, orchards and fields. One specialized group — moss mites *(Oribatida)* — lives in soil and consumes decaying organic matter. Their populations in soil can be immense, reaching up to half a million per square meter, making these particular mites economically important invertebrates. Additionally, mites found in homes are a major sources of allergens.
