Kalligrammatidae

Kalligrammatidae, sometimes known as kalligrammatids or kalligrammatid lacewings, is a family of extinct insects in the order Neuroptera (lacewings) that contains twenty genera and a number of species. The family lived from the Middle Jurassic to the early Late Cretaceous before going extinct. Species of the family are known from Europe, Asia, and South America. The family has been occasionally described as "butterflies of the Jurassic" based on their resemblance to modern butterflies in morphology and ecological niche.

== Range == The known distribution of Kalligrammatidae is widespread both in time and in location. Fossils of the family have been recovered from sediments in Western Europe, the British Isles, Central Asia, and China. The majority of described species, thirty one, are from Jurassic and Cretaceous fossils found in China. Eight species are known from Kazakhstan, the second largest number of species for a single country, while only two species are represented by fossils found in Russia, though only one is described due to the incomplete nature of the other specimen. One species has been described from Mongolia. Species from Europe are much less common, with four species from Germany and one species from England. Only one genus has been described from the Western Hemisphere, with two species found in Brazil. Six of the genera have been found at two or more locations; Kalligrammula and Kalligramma are the most widely distributed genera.
