Pulicidae, commonly known as flea family, consists of small, wingless insects that are known for their ability to jump long distances relative to their size. They are ectoparasites, primarily feeding on the blood of mammals and birds. Fleas have a laterally compressed body, which helps them move through the fur or feathers of their hosts. The most well-known member of the Pulicidae family is the cat flea (Ctenocephalides felis), which infests domestic pets. Fleas can transmit various diseases and parasites, making them significant in veterinary and public health. Their life cycle includes egg, larva, pupa, and adult stages, allowing them to reproduce rapidly.
