Migrating Butterflies Love Rabbitbrush

"Kathy, I was at your plant walk Saturday at Devil's Backbone and today, there are hundreds, maybe thousands of butterflies there!"

I'd just picked up the phone in mid morning, Sept. 22. To be alerted by Sandy to the butterfly migration.

I'd read something about a butterfly migration in the Denver Post : more than the usual number of painted lady butterflies moving south along the Colorado Front Range.

I went to see for myself.
