Lipoptena cervi, the deer ked or deer fly, is a species of biting fly in the family of louse flies, Hippoboscidae. These flies are commonly encountered in temperate areas of Europe, Siberia, and northern China. They have been introduced to North America. [12] They are parasites of elk, deer, and other deer family members, burrowing through the fur and sucking the blood of the host animals. Adults are only 5–7 mm (0.20–0.28 in) in length and brownish in colour. Their bodies are flat and elastic, making their removal difficult. L. cervi is a poor flier and can only fly for short distances. Once the insect reaches its target, it sheds its wings and starts burrowing through the fur.
Although their life cycle depends on deer, they may on rare occasions bite humans, producing responses ranging from unnoticeable to highly allergic. Initially, the bite may be barely noticeable and leaves little or no trace. Within 3 days, the site may develop into a hard, reddened welt. The accompanying itch is intense and typically lasts 14 to 20 days. Occasionally, an itch papule may persist for up to a year. [13] The main annoyance in humans is the inconvenience and unpleasantness of removing keds from hair and clothes.
Anaplasma phagocytophilum , a Gram-negative, obligately intracellular bacterium that causes anaplasmosis, has been detected in L. cervi, as has Borrelia burgdorferi , the causative agent of Lyme disease, [14] but whether the insect can serve as a vector is as yet unknown.
Horses can develop colic after a bite. [15] Dogs that are bitten may develop a moderate to severe dermatitis. [15] And L. cervi can attain Bartonella schoenbuchensis from biting deer. [13] Much, however, remains unknown about the ked's potential to pose a medical or veterinary threat.
Remains of L. cervi have been found on Ötzi, the Stone Age mummy from the Schnalstal glacier in South Tyrol. [16]
Both males and females of L. cervi consume blood from their hosts. Feeding lasts 15 to 25 minutes. [13] The female produces one larva at a time and retains the developing larva in her body until it is ready to pupate. The larva feeds on the secretions of a "milk gland" in the uterus of its mother. The female gives birth to a fully mature white prepupa. She may produce larvae for as long as 10 months. A newborn prepupa immediately darkens, forms the puparium, and begins to pupate on the forest floor, or where the deer are bedded. After pupation, the winged adult emerges and flies in search of a host. Upon finding a host, the adult fly breaks off its wings and it is permanently associated with its host. [17]
This species is found in most of Europe (including Great Britain and Ireland), as well as Algeria, eastern Siberia, and northern China. It was introduced to and is established in the Eastern United States (New Hampshire, Massachusetts, Pennsylvania, Idaho, and New York). [18] It also spread to Finland from Russia in the early 1960s, where it primarily feeds on moose, though it is spreading to reindeer. [17] [19] [20]
Red deer, elk (moose), roe deer, fallow deer, and Siberian musk deer are this fly's native hosts. In the United States, it has acquired hosts such as Canadian deer, white-tailed deer, and reindeer. [17] [18] There are stray records of bites on humans, dogs [21] and badger, and it will occasionally commit to the wrong host. [20]
Hippoboscoidea is a superfamily of the Calyptratae. The flies in this superfamily are blood-feeding obligate parasites of their hosts. Four families are often placed here:
A black fly or blackfly is any member of the family Simuliidae of the Culicomorpha infraorder. It is related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. They are divided into two subfamilies: Parasimuliinae contains only one genus and four species; Simuliinae contains all the rest. Over 1,800 of the species belong to the genus Simulium.
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.
Lipoptena is a genus of flies in the family Hippoboscidae, known as louse flies or keds
Crataerina pallida, the swift lousefly, is a species of biting fly in the family of louse flies Hippoboscidae. These flies are commonly encountered in the nests of the common swift in Europe and Asia.
Hippoboscinae is a subfamily of the fly family Hippoboscidae. All are parasitic, and unlike some other members of the Hippoboscidae, all Hippoboscinae are winged species.
Lipopteninae is a subfamily of the fly family Hippoboscidae. All are parasitic.
Lipoptena mazamae, the Neotropical deer ked, is a fly from the family Hippoboscidae. They are blood-feeding parasites of the white-tailed deer - Odocoileus virginianus in the southeastern United States and Central America, the red brocket deer - Mazama americana in Mexico to northern Argentina, and also an incidental parasite of domestic cattle, Cougars - Puma concolor, and man.
Lipoptena depressa, or the Western American deer ked, is species of fly in the family Hippoboscidae. The flies are blood-feeding ectoparasites of mule deer, Odocoileus hemionus and white-tailed deer, Odocoileus virginianus. They are found in the western United States and Canada.
Neolipoptena ferrisi, or the Pacific deer ked, is a species of fly from the family Hippoboscidae. They are blood-feeding parasites of the mule deer - Odocoileus hemionus, the white-tailed deer - Odocoileus virginianus & The Pronghorn - Antilocapra americana. They are found from British Columbia, Canada, to Baja California, Mexico. and Australia.
Neolipoptena is a genus of flies in the family Hippoboscidae.
Hippobosca equina, also known as the forest fly or New Forest fly, is a biting fly from the family Hippoboscidae. They are blood-feeding ectoparasites of primarily horses and other large mammals including cattle. It is a permanently fully winged fly, not shedding its wings on finding its host, as in some other Hippoboscidae. With its wings retained, it may thus fly away from its host to deposit its larvae. They are good fliers.
Hippobosca is a genus of flies in the family Hippoboscidae, with seven known species. There are numerous synonyms.
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.
Melophagus is a genus of flies in the family Hippoboscidae. All are wingless.
Ornithomyinae is a subfamily of the fly family Hippoboscidae. All are blood feeding parasites, for the most part on birds, though some have mammals as hosts.
Hippobosca longipennis, the dog fly, louse fly, or blind fly, is a blood-feeding parasite mostly infesting carnivores. The species name "longipennis" means "long wings". Its bites can be painful and result in skin irritation, it is an intermediate host for the canine and hyaenid filarial parasite Dipetalonema dracunculoides, "and it may also be a biological or mechanical vector for other pathogens".
Many species of flies of the two-winged type, Order Diptera, such as mosquitoes, horse-flies, blow-flies and warble-flies, cause direct parasitic disease to domestic animals, and transmit organisms that cause diseases. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these diseases are high. These problems occur wherever domestic animals are reared. This article provides an overview of parasitic flies from a veterinary perspective, with emphasis on the disease-causing relationships between these flies and their host animals. The article is organized following the taxonomic hierarchy of these flies in the phylum Arthropoda, order Insecta. Families and genera of dipteran flies are emphasized rather than many individual species. Disease caused by the feeding activity of the flies is described here under parasitic disease. Disease caused by small pathogenic organisms that pass from the flies to domestic animals is described here under transmitted organisms; prominent examples are provided from the many species.
Chrysopsinae is an insect subfamily in the family Tabanidae commonly known as deer flies or sheep flies and are bloodsucking insects considered pests to humans and cattle. They are large flies with large brightly-coloured compound eyes, and large clear wings with dark bands. They are larger than the common housefly and smaller than the horse-fly.
Lipoptena grahami is a species of fly in the family Hippoboscidae. It is found in China.
