Butterfly Eruption in Tahoe

There’s a massive eruption of butterflies in Tahoe this week – there are swarms of them all over the place, including on the highways and the trails around Tahoe.  According to this news report, they’re the California Tortoiseshell Butterfly and there may be millions of them around the lake right now.

“It is pretty phenomenal,” said Tahoe Institute of Natural Science (TINS) Executive Director Will Richardson, Ph.D. “It’s exceptional. I have not seen a flight quite like this before.”

Here’s some video I recorded in slow motion while mountain biking the Sawtooth Trail near Truckee yesterday:
