👉 Psyllids are a type of insect that have long, slender bodies and small, round eyes. They are found in various habitats such as forests, swamps, and wetlands, where they feed on a variety of plants and are known for their ability to digest cellulose and lignin from the plant material. Psyllids are also considered an important part of the food chain as they help decompose dead organic matter into nutrients that can be used by other organisms in the ecosystem.
