Simuliidae, commonly known as black flies, are small, blood-feeding insects found in various habitats worldwide. They are typically characterized by their humped backs and short antennae. Black flies are most active in warm weather and are often found near fast-flowing water, where their larvae develop. These insects are known for their painful bites, which can cause allergic reactions in some people. Simuliidae play a significant role in ecosystems as both pollinators and as a food source for various animals. However, they can also be vectors for diseases, such as Onchocerciasis, affecting human health in certain regions.
