👉 A phlegmatist is a type of insect that feeds on exudate, which is a mixture of mucus and saliva. These insects are commonly found in the digestive systems of animals such as birds and mammals. They feed by secreting mucus into their bodies to trap air and food particles, before passing them back through the digestive tract. The phlegmatist's body structure includes a series of glands that produce mucus, which is then expelled from the body through the skin.
