Fairyflies (the family Mymaridae) are tiny, slender wasps in the Chalcidoidea that include the smallest of all insects. There are over 1400 species in ca. 100 genera worldwide. Fairyflies parasitize the eggs of larger insects, primarily Hemiptera. As such, they are among the more important biological control agents known, attacking many pest insects. Chalcidoidea is a superfamily of Hymenoptera There are nineteen families Agaonidae Walker, 1846 Aphelinidae Thomson, 1876 Chalcididae Latreille, 1817 Encyrtidae Walker, 1837 Eucharitidae Latreille, 1809 Eulophidae (including Elasmidae) Westwood, 1829 Eupelmidae Walker, 1833 Eurytomidae Walker, 1832 Leucospidae Fabricius, 1775 Mymaridae Haliday, 1833 Ormyridae Forster, 1856 Perilampidae Latreille, 1809 Pteromalidae Dalman...

They are not strong fliers and are generally moved through the air by the prevailing winds. Their forewings are paddle-shaped, with a long fringe of hinged setae around the outer margin to increase the surface area during the downstroke. There are several aquatic genera, some species of which "fly" underwater (the difference between air and water is minimal at such small sizes), others of which use their legs to paddle. A seta is a stiff hair, wierd, culy, things bristle, or bristle-like process or part of an organism. ...

In Dicopomorpha echmepterygis, a species from Illinois, the males are blind and wingless and may be no more than 0.139 mm in length, the smallest known adults of any insect. Their tiny bodies, neatly packaged with complete digestive, reproductive, respiratory and circulatory systems are actually smaller than a single-celled paramecium. Obviously, the eggs and larvae of this wasp are considerably smaller than the adult. Other species in the family can have bodies as long as 5.5 mm, not including the ovipositor.
