Mesochrysopidae is an extinct family of lacewings known from the Jurassic and Cretaceous periods. They are considered to be closely related to green lacewings of the family
Chrysopidae
Green lacewings are insects in the large family (biology), family Chrysopidae of the order (biology), order Neuroptera. There are about 85 genera and (differing between sources) 1,300–2,000 species in this widespread group. Members of the Genus ...
