Bat flies are members of the insect order Diptera, the true flies, which are external parasites of bats. Two families of flies are exclusively bat flies: Nycteribiidae and Streblidae. [1] Bat flies have a cosmopolitan distribution, meaning that they are found around the world. [2] Nycteribiidae and Streblidae are members of the superfamily Hippoboscoidea, along with the families Hippoboscidae and Glossinidae. [3]
Calyptratae is a subsection of Schizophora in the insect order Diptera, commonly referred to as the calyptrate muscoids. It consists of those flies which possess a calypter that covers the halteres, among which are some of the most familiar of all flies, such as the house fly.
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:
Adenotrophic viviparity means "gland fed, live birth". This is the reproductive mode of insects such as tsetse flies (Glossinidae), keds (Hippoboscidae) and bat flies as adenotrophic viviparity is a characteristic feature of the superfamily Hippoboscoidea.
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 Streblidae are a family of flies in the superfamily Hippoboscoidea, and together with their relatives the Nycteribiidae, are known as bat flies. They are winged or wingless ectoparasites of bats, and often have long legs. They appear to be host-specific, with different species of bat flies occurring only on particular species of bat hosts, sometimes with multiple species of flies sharing a host bat.
Nycteribiidae is a family of the true fly superfamily Hippoboscoidea are known as "bat flies", together with their close relatives the Streblidae. As the latter do not seem to be a monophyletic group, it is conceivable not to unite all bat flies in a single family.
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. 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.
The Egyptian tomb bat is a species of sac-winged bat in the family Emballonuridae. It is a medium- to large-sized microbat with a mass of approximately 30 g (1.1 oz). It is an aerial insectivore, foraging in open space. Based on individuals captured in Ethiopia, it is thought to feed predominantly on Lepidoptera, but is also known to feed on Isoptera, Coleoptera and Orthoptera.
Crataerina is a genus of louse flies in the family Hippoboscidae. All are parasites of birds, feeding on the blood of various species of Apodidae (swifts) and Hirundinidae. The genus is sometimes spelled Craterina.
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.
Basilia is a genus of bat flies in the family Nycteribiidae.
Pseudolynchia canariensis, the pigeon louse fly or pigeon fly, is a species of biting fly in the family of louse flies, Hippoboscidae.
Melophagus is a genus of biting flies in the family of louse flies, Hippoboscidae. There are three known species and one subspecies. All are parasites of bovids. 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.
Gloeandromyces is a genus of fungi in the family Laboulbeniaceae. The genus contains five species. All species are associated with Neotropical bat flies.
The Haemosporida are an order of intraerythrocytic parasitic alveolates.
Vetufebrus is an extinct genus of haemospororida in the family Plasmodiidae. At the time of its description the new genus comprised a single species Vetufebrus ovatus known from a single Miocene Dominican amber fossil found on Hispaniola. V. ovatus was vectored by Enischnomyia stegosoma, the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. V. ovatus is the first instance of a Streblidae bat fly as a host for a malarial parasite.
Nycteribia kolenatii is a species of fly in the family Nycteribiidae. It is found in the Palearctic.
Basilia fletcheri is parasitic bat fly in the genus Basilia, in the subgenus Basilia. It is found in India.
Enischnomyia is an extinct genus of bat fly in the family Streblidae. At the time of its description the new genus comprised a single species, Enischnomyia stegosoma, known from a single Miocene fossil found on Hispaniola. E. stegosoma was the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. The species is host for the plasmodiid Vetufebrus ovatus preserved in its salivary glands and midgut.
