Fairyfly
Mymaridae, commonly known as fairyflies or fairy wasps, is a family of chalcid wasps found in temperate and tropical regions throughout the world. It contains around 100 genera and 1424 species. All of them are parasitoids of the eggs of other insects. Several species have been successfully used as biological pest control agents.
Like most chalcid wasps, fairyflies are very tiny insects, averaging at only 0.5 to 1.0 mm (0.020 to 0.039 in) long. They include the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in).
