INSECTS

Hypoderma species

Insects, despite their fragility, are common fossils in some fresh water deposits and are well represented in amber. The earliest insects are found in the Devonian deposits of Scotland. They became numerous in the Carboniferous coal swamps.

This picture, showing a Hypoderma species in the larval stage, is of a dipteran insect from the Eocene Green River area of the U.S.A.
