MEET THE ANIMAL
Meet Kalligramma
Kalligramma was a large prehistoric lacewing with beautifully patterned wings. One Middle Jurassic species from China, Kalligramma elegans, is known from an incomplete forewing. The preserved part is 75 millimeters long, and researchers restored the complete wing at about 90 millimeters. Its dark central spot and smaller surrounding spots survive in the fossil. A single wing measurement must not be mistaken for the length of the whole insect. [D1]
These insects looked rather like butterflies, but they belonged to a different insect order. Researchers compared their wings and long feeding mouthparts with those of later butterflies. The mouthparts suggest drinking fluids associated with seed plants such as gymnosperms. Helping move pollen is a reasonable ecological interpretation, although it does not identify every plant visited by an individual insect. [D2]
The evidence leaves much of the life cycle open. A broad study of related lacewings does not supply Kalligramma eggs, larvae or cooperative groups. Wing patterns may have helped in defense, but that idea is different from an observed behavior. A reconstruction can show the likely adult outline while keeping these questions visible. [D3]

How to read the evidence
Source supported identifies a description documented by the cited source. Inferred marks a reconstruction or functional estimate. Debated marks competing interpretations. Not established means the sources reviewed for this dossier do not support a firm conclusion; it does not mean a behavior never occurred.
A size reference is an estimate, not a population range. Nesting evidence does not by itself establish courtship, mate choice, or lifelong pairing.
Body mass
Not establishedNot established here
The focal wing fossil does not yield a defensible body-mass estimate. [D1]
Diet
InferredPlant-fluid feeding inferred
Sucking mouthparts in studied relatives and genus examples fit gymnosperm pollination drops; precise meals remain uncertain. [D2]
Habitat
InferredMesozoic gymnosperm vegetation
Daohugou wing fossils establish regional occurrence; a woodland feeding scene is an ecological reconstruction. [D1]
Movement
InferredFlight inferred from wings
Broad forewings and hind wings support flight; a numerical flight speed is unknown. [D2]
Distinctive anatomy
Source supportedVeined wings with patterned eyespots
K. elegans has a central eyespot and surrounding spots; missing body anatomy is comparative. [D1]

THE STORY IN THE FOSSILS
A pattern is not a butterfly
Similar wing patterns and feeding tools can arise in different insect lineages. Resemblance alone does not make a lacewing a butterfly. [2]
A note on scale and time
The dossier identifies the scope of each reference estimate. A mount, an individual fossil and a species-wide adult range are different measurements. Comparison metrics remain unavailable where adult scope has not been established. Unknown does not mean zero.
