Nannochoristidae is a family of

Fossils indicate that Nannochoristidae formerly had a wider distribution, being present in the Northern Hemisphere during the Jurassic and Early Cretaceous.^[3]

Some research suggests the nannochoristids are the only

. The presence of compound eyes in nannochoristid larvae suggests the timing of the development of adult features can be initiated earlier in development, which has important implications for insect evolutionary development.

Phylogeny

The

Antliophora	Diptera (true flies) Mecoptera Nannochoristidae Pistillifera (scorpionflies, hangingflies) Boreidae (snow scorpionflies) Siphonaptera (fleas)

A more recent study in 2021 found Nannochoristidae to be the sister group to fleas, with strong support.[1]
