Echidnophaga gallinacea, also known as the hen flea or sticktight flea, is part of the 2,500 known flea types in the Siphonaptera order. Echidnophaga gallinacea appear dark brown in colour and is a small flea measuring approximately 2 millimetres in length, which is half the size of the common cat flea . [ 1 ]
Flea bites cause a slightly raised, swollen, irritating nodule to form on the epidermis at the site of each bite, with a single puncture point at the centre, like a mosquito bite. [ 34 ] : 126 This can lead to an eczematous itchy skin disease called flea allergy dermatitis , which is common in many host species, including dogs and cats. [ 29 ]
The larva of the cat flea has a grub-like appearance and is ~2 mm in length. The larvae are negatively phototaxic/phototropic, avoiding light and hiding in the substrate around them. The larvae require adequate ambient moisture and warmth, and will die at temperatures near freezing. [8] Cat fleas prefer soil moisture content between 1-10%. [12]
The flea larva has two pharynx chambers, where the posterior one is important for suction. [7] After each moulting period, there is a cost of partial replacement of digestive cells for the new regenerative cells produced during this period. [7] The larva has a two-chambered poorly-developed heart with a dorsal blood vessel. [7]
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
The dog flea (Ctenocephalides canis) is a species of flea that lives as an ectoparasite on a wide variety of mammals, particularly the domestic dog and cat. It closely resembles the cat flea , Ctenocephalides felis , which can live on a wider range of animals and is generally more prevalent worldwide.
From ticks to spiders to bed bugs, here’s what the most common bug bites look like in photos, the symptoms to know, and whether or not they can be dangerous.
Larvae eventually form pupae, which are in cocoons that are often covered with debris from the environment (sand, pebbles, etc.). The larval and pupal stages are completed in about 3–4 weeks when the adults hatch from pupae, then must seek out a warm-blooded host for blood meals. The flea eggs are about 0.5 mm in length.
