Copyright © 2008 Karl Volkman

Fossil Chironomidae?? Pupae
Klondike Mountain Formation, 49 milliion years old, Ferry County, Washington, USA
Size: 10mm
The 1994 possible Chironomidae Pupae specimen.

One layer at the fossil site, very fine grain ashy one with excellent preservation ablility, has been fond that occasionally produces these larva.

The environment which this specimen lived in was upland subtropical/temperate, think SE Asia and SE USA combined, subtropical mixed broadleaf forest with a strong coniferous segment
