Chresmoda is an extinct genus of insects within the family Chresmodidae.

Description

Chresmoda are large enigmatic insects with very long specialized legs, probably adapted for skating on the water surface. They can reach a body length of about 25 millimetres (0.98 in), with a forewing length of about 28 millimetres (1.1 in).[1]

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.[2] [3]

They lived during the Cretaceous of Brazil, China, Lebanon, Spain, United Kingdom, as well as in the Jurassic of Germany, from 150.8 to 94.3 Ma.[1]
