Diaura

Diaura is a genus of flies belonging to the family Empididae, commonly known as dance flies. Flies in the Diaura genus are typically small to medium-sized, often with a slender build. They are found in various habitats, often near water sources.

Characteristics:

• Morphology: Diaura species generally exhibit the characteristic Empididae features including a proboscis (though its size varies among species), long legs, and a humped thorax. Specific morphological details are crucial for distinguishing between individual species within the genus, and often involve examination of the genitalia.
• Habitat: Diaura flies are commonly found near streams, rivers, and other bodies of water. They are typically associated with damp or moist environments.
• Behavior: Like other Empididae, Diaura flies exhibit swarming behavior, often seen in mating displays. The males frequently present prey items (typically small insects) to the females during courtship.
• Diet: The larval stages are believed to be predatory or scavengers in aquatic or semi-aquatic environments. Adult Diaura flies are often predatory, feeding on other small insects. Males may present prey to females during mating, a behavior common in Empididae.
• Distribution: Diaura species are distributed across various geographical regions, primarily in the Northern Hemisphere. The precise distribution varies based on the specific species.
• Taxonomy: The classification and taxonomic relationships within the Diaura genus are subject to ongoing research and may be revised as new information becomes available. Determining species-level identification often requires expert knowledge and microscopic examination of specimens.
