Genera

Description

Chresmodidae are large enigmatic insects with very long specialized legs, probably adapted for skating on the water surface. They can reach a size of about 14 centimetres (5.5 in).[5]

These Polyneoptera of uncertain position have been considered aquatic and terrestrial bug or phasmids. They should instead be anomalous paraplecopterids living on the water surface, probably predaceous on nektonic small animals.[6][7]

They lived during the Cretaceous of Brazil, China, Lebanon, Spain, United Kingdom, as well as in the Jurassic of Germany and the Triassic of Kyrgyzstan, from 235.0 to 94.3 Ma.[1]
