We Have Been Invaded By Butterflies

Our backyard was ground zero for a huge butterfly migration today. Here is stunning wide-screen, Dolby-enhanced, Technicolor proof:

OK, fine, it doesn’t look all that impressive. But there were lots of them! And they were definitely on a mission, with no dilly-dallying. My back-of-the-envelope guess is that the entire flock must have included a million butterflies or more.

I’m not sure what kind they were, but they were kind of smallish and had black and orange markings. What kind of butterfly migrates north through Orange County near the Ides of March?

UPDATE: The LA Times has the story:

Those black-and-orange insects that seem to be everywhere you look in Southern California aren’t monarchs and they aren’t moths. They are called Painted Ladies, and these butterflies are migrating by the millions across the state.

The migration itself is nothing new. Painted Ladies set off from their wintering grounds in the Mojave and Colorado deserts of southeastern California as winter gives way to spring. They travel roughly the same path every year, flying northwest to Sacramento en route to Oregon, Washington and beyond. (They’ve been spotted as far north as Alaska.)

What’s unusual this year is the number of two- to three-inch butterflies making the journey. Scientists say there haven’t been this many Painted Ladies traversing the state since 2005, when the population climbed to about 1 billion.

So there you have it.

$500,000 MATCHING GIFT

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones: A special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of the huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
