Midges (Chironomidae) resemble mosquitoes but have no wing scales. Chronomids are very common everywhere and can frequently be found in large swarms at dusk around water. Males have feathery antennae and a slender body while females have hairy antennae and a stout body. The elongate wings lie flat or are held slightly raised over the abdomen.
Pupae are called buzzers. A few species can be pests however they are an important source of food for trout. They have a body length of 1mm to 9mm. In the UK there are 400 species and over 4,000 species world-wide.
