High Sierra Butterfly Identification & Resources


High Sierra Nevada All Living Things Forum



 The whole web of life is being distorted by the  changing character of the seasons on and around the the vastness of the North Pacific Ocean.

 The Sierra Nevada Mountain Range is a significant element in the complex relationship of the North Pacific Ocean weather patterns with the North American continent.

 The relationship between North Pacific weather patterns and the High Sierra is vitally important for the vast overlapping webs of social and natural life depending on bountiful and predictable weather patterns.
These predictable and bountiful resources no longer exist on their own, in Nature, nor in the context of the vast populations to overwhelm Nature that we have spawned.

We have overwhelmed Nature and its resources fundamentally and on its face..

Butterfly numbers down by two thirds,
Technical University of Munich (TUM), March 20, 2019.


The Germs
“...home to roughly 33,500 species of insects”

Going Down Hard
“...but their numbers are decreasing dramatically. Of the 189 species of butterflies currently known from Germany, 99 species are on the Red List, 5 have already become extinct, and 12 additional species are threatened with extinction.”

When it comes to Monarchs, Fall Migration Matters,

Huge Declines
“Monarch butterflies in eastern North America have declined by 84% on Mexican wintering grounds since the observed peak in 1996.”

Florida Monarch Butterflies dropped 80 percent since 2005


Long Disaster tied to Human's Glyphosate & Climate Effects Disrupting Milkweed

Florida monarch butterfly populations have dropped 80 percent since 2005,
Florida Museum of Natural History, November 8. 2018.


Radical Decline
"A 37-year survey of monarch populations in North Central Florida shows that caterpillars and butterflies have been declining since 1985 and have dropped by 80 percent since 2005."

"...decrease parallels monarchs' dwindling numbers in their overwintering grounds in Mexico."

Milkweed Connection
"This study shows the tight connection between monarchs and milkweed and highlights very dramatic losses in abundance in Florida that further confirm the monarch is declining."

Herbicide Glyphosate & Milkweed
"...shrinking native milkweed populations and a boost in glyphosate use in the Midwest are part of the problem."

" lethal to milkweed, the monarchs' host plant."

Butterfly, Satyr Anglewing, High Sierra, Clarks Fork Stanislaus River

Finding my way North down from the top of the Clarks Fork Headwaters Bowl to the beginning of the Clarks Fork of the Stanislaus River brought me through some rough terrain.

After finding my way down through a channel between the steep cliffs protecting the headwaters I approached the burbling creek that begins the Clarks Fork's voyage down-mountain when this beautiful butterfly flew by.
