An illustration of the 'feather-winged' Mymar pulchellum by John Curtis, circa 1840

Mymarilla wollastoni: (1) Female exhibiting the extraordinarily densely hairy (setose) and domed forewings peculiar to the species. (2) Close-up of the thread-like antennae of a male. Mymarilla wollastoni is endemic to the island of Saint Helena in the southern Atlantic. Scale bar = 1000 μm

Cremnomymar sp. (female) exhibiting the usual macropterous and flat wings of fairyflies. Scale bar = 1000 μmGreatly reduced (micropterous) wings on Paracmotemnus sp. (female)

The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcid wasps found in temperate and tropical regions throughout the world. It contains around 100 genera with 1400 species.

Fairyflies are very tiny insects, like most chalcid wasps. They average 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), and the smallest known flying insect, only 0.15 mm (0.0059 in) long. They usually have nonmetallic black, brown, or yellow bodies. The antennae of the females are distinctively tipped by club-like segments, while male antennae are thread-like. Their wings are usually slender and possess long bristles, giving them a hairy or feathery appearance, although some species may have greatly reduced stubby wings or lack wings altogether. They can be distinguished from other chalcid wasps by the H-shaped pattern of sutures on the front of their heads.
