Orbellia

Orbellia is a genus of flies belonging to the family Heleomyzidae. These small to medium-sized flies are found primarily in the Holarctic region, though some species occur elsewhere.

Characteristics: Orbellia flies typically possess characteristics common to the Heleomyzidae family, including a bristly body and legs, and a relatively long proboscis. They are generally yellowish or brownish in color. Key features used in species identification often involve the arrangement of bristles on the head, thorax, and legs, as well as wing venation patterns.

Habitat and Ecology: Orbellia species are often associated with damp environments and decaying organic matter. Larvae are saprophagous, feeding on decaying vegetation, fungi, or other organic material. Adults may be found in woodlands, meadows, and other similar habitats. The specific ecological roles of different Orbellia species are not always well-documented.

Classification: The classification of Orbellia within the Heleomyzidae family is subject to ongoing research and revision. The exact number of species included in the genus and their relationships to other genera within the family can change as new data become available. Taxonomy is primarily based on morphological characteristics.

Research and Importance: While Orbellia flies are not generally considered to be of major economic or medical importance, they play a role in decomposition and nutrient cycling within their ecosystems. Further research is needed to fully understand the diversity, distribution, and ecological roles of these flies. They contribute to the overall biodiversity of their respective habitats.
