Field trip: Butterflies along the Beeline Highway with Ron Rutowski
Saturday, March 25, 2017
8:30 AM - 2:30 PM
Spring starts early in the Upper Sonoran Desert. By March many wildflowers are in bloom and on warm days the spring butterflies – Orangetips, Marbles, Spring Azures, Variable Checkerspots, etc. - are out in force. This month the CAzBA field trip is to Round Valley in the Mazatzal Mountains, just at the upper elevational limit of the Sonoran Desert. Here, there is stream-side riparian vegetation, stands of mesquite on the flood plain, and hillsides dotted with cacti and annual wildflowers, all of which makes for a rich and accessible butterfly community. This area is about 50 miles from Phoenix where the Beeline highway crosses Sycamore Creek, right before the road climbs to Sunflower Valley. We will explore a side drainage of Sycamore Creek where Variable Checkerspots and Empress Leilia will be common. After that, we will drive up to Sunflower and walk on the "old" Beeline to the ranger station. At the ranger station, we will sit down at the picnic tables for lunch. Sagebrush Checkerspot (pictured) and Zela Metalmark are some of the regulars there. Please gather at the Denny's on Shea Blvd. in Fountain Hills at 8:30AM. Wear sturdy shoes, bring water, snacks/lunch and close focus binoculars. For questions, please email Ron Rutowski at email@example.com. We ask for a $5 donation.
