life science Maturity 11-13 Next article →

A midge is a very small fly. This name covers many different types of flies. They live on almost every part of land. They only avoid very dry deserts. They also stay away from freezing cold zones. Midges are important to the world around us. They play many different roles in nature.

Many midges follow a life cycle in the water. Most midges are aquatic during their larval stage. This means they live in water when they are young. Some young midges are called bloodworms. They have hemoglobin in their bodies. This is the same thing that makes blood red. After they grow, they become flying adults.

Different midges have very different jobs. Some are called detritivores. This means they help move nutrients through the earth. Other midges are food for other animals. Frogs and swallows like to eat them. Some midges also help plants grow. They act as pollinators for the cocoa tree. This helps farmers grow more crops.

Not all midges are helpful to humans. Some belong to the family Ceratopogonidae. These are often called biting midges. In North America, people call them no-see-ums or punkies. In Australia, they are called sandflies. These midges can suck blood from humans and mammals. They can also spread diseases to livestock. This includes blue tongue and African horse sickness.

Midges can sometimes appear in huge numbers. In May 2025, many midges appeared in Osaka, Japan. This happened at the World Exposition. Such a large group can cause quite a bit of mayhem. You might see non-biting midges near lakes or ponds. They are often just a minor nuisance. They are a big part of our natural world.
