The following is from the U.S.Fish & Wildlife Service:
DENVER – Both the meltwater lednian stonefly and the western glacier stonefly are tiny winged insects about the size of your pencil eraser. They live in mountain-top streams and lake outlets where the frigid waters are fed from glaciers and permanent snowfields in and near Glacier National Park, in northwest Montana.

The good news is four potential new populations of the western glacier stonefly are believed to have been found in the Beartooth Mountains in southwestern Mont., and Grand Teton National Park, Wyo. These stoneflies are found almost entirely on federal land in places so remote they are protected from you and me. The bad news is their glaciers are melting, putting the icy streams where stoneflies thrive in danger from drought and climate change.

Because of these threats, the U.S. Fish and Wildlife Service (Service) is proposing a rule to list the meltwater lednian stonefly and western glacier stonefly as threatened under the Endangered Species Act. A threatened listing means the stoneflies are likely to become endangered within the foreseeable future throughout all or a significant portion of their range.

The Service is asking for your help by sending us any scientific or commercial information you may have on these two stoneflies during the 60-day public comment period that opens tomorrow when the rule publishes in the Federal Register, and is requested by December 1, 2016.

Starting tomorrow, you can see our proposed listing rule HERE. Submit comments by clicking on the “Comment Now!” button.
Or, you can mail your comment to:

Falls Church, VA 22041-3803.
The Service will post all information received HERE , including any personal information that is provided.
Remember the four potential new populations of western glacier stonefly found? Once the Service fully analyzes the new information, we will reopen the public comment period on the proposed listing rule. This new data will also help the Service determine critical habitat and potential economic impacts. Our goal is to make a final decision on whether or not to list the stoneflies as threatened within one year.
You can learn more about the stoneflies HERE and HERE.
