Rancho San Antonio Open Space Preserve
Santa Clara County, CA

Pleasantly warm day, enjoyed seeing 4 very fresh California Tortoiseshells. Unfortunately the Open Space people have begun mowing the trail-side vegetation, which does not bode well for future butterflying at Rancho San Antonio this season.
