2022 PeerJ  
Fossils of adults of Elmidae are already known from amber, however a record of immatures was so far lacking. We report here the first fossil larva of Elmidae, preserved in Baltic amber.  ...  The new fossil has similarities in the general body shape and the prominent characters with some modern larvae of Elmidae.  ...  We acknowledge DESY (Hamburg, Germany), a member of the Helmholtz Association HGF, for the provision of experimental facilities. Parts of this research were carried out at beamline p05.  ...
