Fleas are wingless insects, 1.5 to 3.3 millimetres (1 ⁄ 16 to 1 ⁄ 8 inch) long, that are agile, usually dark colored (for example, the reddish-brown of the cat flea), with a proboscis, or stylet, adapted to feeding by piercing the skin and sucking their host's blood through their epipharynx.
Fleas (Siphonaptera) such as Echidnophaga gallinacea, range from 2–6 millimetres in length and have bodies which are flattened laterally or appear compressed horizontally when viewed from above. [9] [12] The flea's body is designed to easily travel through hairs or feathers, allowing free movement throughout the host's body.
Cat fleas are holometabolous (undergo complete metamorphosis) insects and therefore go through four life cycle stages of egg, larva, pupa, and imago (adult). Adult fleas must feed on blood before they can become capable of reproduction. [10] Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults. [11]

Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
Although many species of flea require a blood meal before they can copulate, that is not the case with Ceratophyllus gallinae. [6] As with other fleas, the life cycle consists of eggs, the larval stages, a pupal stage and an adult stage. [7] The larvae have chewing jaws and it is only the adult fleas that are capable of biting the host.
Blood-sucking arthropod vectors including fleas, mosquitoes and ticks are thought to be the primary mode of dissemination of M. haemofelis. [5] Transmission from queen to kitten has also been observed, however, it is unclear whether this takes place in utero , during birth or through nursing.
