Blephariceridae

Blephariceridae is a family of flies belonging to the order Diptera. They are commonly known as snag flies or snag gnats, and are characterized by their small size, typically ranging from 1 to 3 millimeters in length. The family includes around 150 species, which are distributed worldwide, with the highest diversity found in the tropics.

The larvae of Blephariceridae are aquatic and are often found in temporary pools of water, such as those created by rain or melting snow. They are predators, feeding on other small aquatic invertebrates. The adults are also aquatic and are often found near the water's surface, where they feed on nectar and other small particles of organic matter.

Blephariceridae are of interest to scientists due to their unique life cycle and their role in aquatic ecosystems. They are also of interest to entomologists and taxonomists due to the diversity of their species and the challenges they present in terms of classification and identification.
