BUTTERFLY NEWS
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..
This overlap has proven destructive for the natural web of life, butterflies especially.
Our local changes are linked to broader regional changes in wind direction and temperatures that influence all Natural living things near and far, and especially the butterflies who travel so far.
Our favorite source for fundamental information, insight, and references about High Sierra butterflies is Doc Shapiro's website for his multi-decade project of studying Sierra Butterflys.
Below we collect and store butterfly news and information we encounter in the popular and science press.
Please post up any butterfly news you encounter!

CAPTIVE-BRED MONARCHS
No Domesticated Replacements for Declining Wild Monarchs
Direct to Research
Monarch Butterflies Bred in Captivity may Lose the Ability to Migrate, study finds,
University of Chicago, June 24, 2019.
MAIN POINTS
Not Migratory
"...butterflies purchased from a commercial breeder did not fly in a southward direction, even in offspring raised outdoors..."
"...North American monarch population has declined 90% over the last two decades."
"Monarchs breed during the summer and autumn, the autumn generation being the one that migrates."
Domesticated Monarchs
"These monarchs have been brought into captivity and prevented from migrating for many generations, and they have genetically lost migration. It's a microcosm for what's happening naturally."
"We can't point to a single genetic change that did it because there are lots of them," he said. "But we think somewhere buried in the genome are changes that have broken it."
Not Helping
"It looks like buying monarchs to raise and release doesn't contribute to the migratory population, and raising them indoors probably isn't helpful either."
Some Help
"If you want to grow milkweed in your garden and raise monarchs you find around your house, just don't take them inside. If you keep them outdoors, they should be totally fine."

Setting the Scene
Doc Shapiro's Butterfly Report, 2016, PDF,
"It was a terrible year in the Sierra, marked by low numbers of both species and
individuals everywhere, with many things either not seen at all or in drastically-
reduced numbers."
"...the Sierra, where the butterfly fauna is in free fall. And we can’t blame that free fall on habitat change, or pesticides. It HAS to be climate- (or at least weather-) driven."
