Two fleas have been collected in association with abundant remains of fish, plants, phyllopod Crustacea (Conchostraca, Anostraca and Cladocera) and other insects in a Lower Cretaceous siltstone at Koonwarra, southern Gippsland, Australia. The insect fauna consists mainly of the aquatic immature stages of Ephemeroptera (mayflies), Diptera (midges ...
