Nycteribia

Nycteribia is genus of insects within the family Nycteribiidae, comprising approximately 35 species, that exclusively parasitize the blood of bats.

== Description == Nycteribia do not have wings, but possess halteres and atrophied flight muscles, suggesting history of flight. Their bodies are divided into a flattened and shielded thorax, with six, tri-segmented, clawed appendages, and an ovular lower abdomen. Their heads are more narrow than other Hippoboscidae, which are attached dorsally to the anterior end of the thorax when at rest and when feeding, the head rotates in a half circle and protrudes forward to attach to the host.
