San Antonio’s Seventh Annual Monarch Butterfly and Pollinator Festival will celebrate the distinctive orange-and-black-winged pollinators’ migration through Texas to Mexico for the winter months. The San Antonio Zoo train that cruises around Brackenridge Park has been made over for the celebration as a striped Caterpillar Train, which will start off the festival celebrations on Saturday with a lap around the park, followed by a People for Pollinators Procession.
