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]
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]
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.
The larvae, commonly called chiggers, are about 170–210 μm (0.007–0.008 in) in diameter, normally light red in color, and covered in hairs; they move quickly relative to size. The larvae congregate in groups on small clods of soil, in matted vegetation, and even on low bushes and plants, where they have more access to prospective hosts.
