Midge flies are small, flying insects belonging to the family Ceratopogonidae. They are often found near water sources, such as ponds and rivers, where they breed. Midge flies are typically less than 1/8 inch long and can be recognized by their slender bodies and long legs. These insects are known for their swarming behavior, especially during warm months. While some species are harmless, others can bite and cause irritation to humans and animals. Midge flies play a role in the ecosystem as both pollinators and a food source for various animals, including fish and birds.
