Two-winged insects belong to the order Diptera and are commonly known as flies. However, there are various synonyms to describe these insects, depending on their size, appearance, or behavior. For instance, midges are small, delicate flies that often swarm in large numbers. Gnats are also small flies, but they have distinctive long legs and are often found near stagnant water. Mosquitoes are larger flies that feed on blood and can transmit diseases to humans. Another synonym for two-winged insects is hoverflies, which have a resemblance to bees or wasps, with black and yellow stripes on their bodies. Whatever the name, two-winged insects are an essential part of the ecosystem and have unique roles in pollination, decomposition, and food webs.
