The domestic silk moth is a species of moth that is commonly used in the production of silk. Argentine ants are very efficient at breaking down organic matter, and they are often used in pest control to help control other ant species. Mites help to break down these materials so that they can be used by plants to grow. Clothes moths are attracted to fabrics made of natural materials such as wool, fur, and feathers. [5], The indigenous Texas trailing phlox (Phlox nivalis texensis), an endangered species, grows in the sandy soils of longleaf pine forests. There are many fungi that are helpful.
