Dolicopidae

Dolicopidae is a family of flies belonging to the order Diptera. These flies are commonly known as long-legged flies due to their distinctive slender and elongated legs, which give them their characteristic appearance. The family comprises a moderate number of species distributed across various regions of the world, with a notable presence in temperate and tropical areas.

Adult Dolicopidae are typically small to medium-sized insects. Their bodies are often slender and may exhibit metallic coloration, although this varies among species. A key feature of Dolicopidae is their large, prominent eyes, which are usually contiguous in males. The wings are generally clear or slightly infuscated, and the venation follows a pattern typical for the brachyceran suborder.

The larvae of Dolicopidae are less well-studied than the adults. They are generally found in damp environments, such as soil, decaying organic matter, or aquatic habitats. Their feeding habits are diverse, with some species being predatory on other invertebrates, while others may be detritivores.

Adult Dolicopidae are frequently observed in open, sunny areas, often resting on vegetation or the ground. They are active predators, feeding on small insects, mites, and other arthropods, which they capture with their agile movements. Their long legs are adapted for quick running and jumping, aiding in both hunting and escaping danger. While not considered pests, their predatory nature plays a role in regulating populations of smaller invertebrates in their ecosystems.
