Kalligrammatidae

Definition

An extinct family of large lacewings (order Neuroptera) that lived from the Middle Jurassic to the early Late Cretaceous, characterized by broad, scaled wings and a striking convergent resemblance to modern butterflies in both morphology and presumed pollination ecology.

Etymology

Example

Kalligrammatidae includes genera such as *Kalligramma* and *Oregramma*, whose fossils from Chinese and German Jurassic deposits preserve detailed wing patterns and mouthpart structures suggesting nectar-feeding habits.

Synonyms

• kalligrammatid lacewings

Related Terms

• Neuroptera
• lacewing
• Convergent evolution
• Jurassic insects
• Saurophthiridae
• pollination syndrome

Usage Notes

The common nickname "butterflies of the Jurassic" reflects morphological convergence, not phylogenetic relationship; Kalligrammatidae are true lacewings, not lepidopterans. The family is sometimes grouped with the related Saurophthiridae in the superfamily Kalligrammatoidea. Extinction occurred before the end-Cretaceous mass extinction event.
