Hippoboscidae
__NOTOC__ Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds. In this family, the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic. As usual in their superfamily Hippoboscoidea, most of the larval development takes place within the mother's body, and pupation occurs almost immediately. The sheep ked, ''Melophagus ovinus'', is a wingless, reddish-brown fly that parasitizes sheep. The Neotropical deer ked, ''Lipoptena mazamae'', is a common ectoparasite of white-tailed deer (''Odocoileus virginianus'') in the southeastern United States. Both winged and wingless forms may be seen. A common winged species is ''Hippobosca equina'', called "the louse fly" among riders. Species in other genera are found on birds; for example, ''Ornithomya bequaerti'' has been collected from birds in Alaska. Two species of the Hippoboscidae – '' Ornithoica (Ornithoica) podargi'' and ''Ornit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melophagus Ovinus
''Melophagus ovinus'', or the sheep ked, is a brown, hairy fly that resembles a tick. This wingless fly is about 4 to 6 mm long and has a small head; it is a fly from the family Hippoboscidae. They are blood-feeding parasites of sheep. The sheep ked feeds on the blood of its host by inserting its sharp mouthparts into capillaries beneath the skin. The legs of the sheep ked are very strong and tipped with claws. Sheep keds live their whole lives in the wool of sheep. They are most commonly found on the neck, shoulders, and underbelly of the host animal. Although they are often referred to as the “sheep tick”, sheep keds spend their entire lifecycle on their hosts, which is distinguishable from the characteristics of a true tick. Additionally, sheep keds have six legs, whereas true ticks have eight legs. Distribution Native to most of Europe including Iceland, and the Faroe Islands, as well as North West Africa, Mongolia, and North India, it was introduced and established ...

Skin Lesion
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions resul ...
