September 1 - Dragonfly Field Guide Author
8:30am. For the past decade ‘Common Dragonflies of the Southwest’ has been the go-to field guide to Arizona Odonata. An excellent, convenient and pocket-size full-color guide, the durable little books became increasingly rare when authors Kathy and Dave Biggs moved to publishing e-Guides. Good news for dragonfly fans: their books are back in stock at Boyce Thompson Arboretum State Park (including just-released ‘Dragonflies of the Greater Southwest - Arizona, California, Colorado, New Mexico, Nevada and Utah’) even better, they'll visit BTA for a rare meet-the-authors book signing and guided dragonfly walk Tuesday morning, Sept. 1. Bring your dog-eared field edition to be personalized and autographed that morning – or pick up a pristine new copy; the pocket guide runs about $12, while the expanded new book is $24. Attending the 9am guided tour with these odonate experts is free when you show your AZ State Parks annual pass - or included with $10 daily admission for all other visitors. Be in the visitor center breezeway lobby from 8:30-9am. for the book signing and informal ‘meet the authors” half-hour; the Tuesday special dragonfly walk begins at 9am. What’s possible this time of year? An August report last year included Red-tailed Pennant, Western Pondhawk, Neon Skimmer; Flame Skimmer, Straw-colored Sylph, Roseate Skimmer, Blue Dasher, Spot-winged Gliders, Mexican Amberwings, Black Saddlebag, Giant Darners – and about a dozen other species.

A variety of plants from the world's deserts await you at Boyce Thompson Arboretum State Park.
Boyce Thompson Arboretum State Park is the place to discover the intricate beauty and many faces of Arizona's oldest and largest botanical garden. Featured are plants from the world's deserts, towering trees, captivating cacti, sheer mountain cliffs, a streamside forest, panoramic vistas, many natural habitats with varied wildlife, a desert lake, a hidden canyon, specialty gardens and more.
The Arboretum was founded in the 1920s by mining magnate Col. William Boyce Thompson. In 1917 Col. Thompson served as co-leader of a Red Cross mercy mission to Russia, where he came to understand the importance of plants as the ultimate source of a large portion of mankind's food, clothing, and shelter. It was then, that he determined to use his great wealth to improve the use of plant resources. The Arboretum is one of his legacies.
Encompassing 323 acres, the Arboretum is Arizona's oldest and largest botanical garden. It was the first purely botanical institution in the inter-mountain states. The Arizona State Parks Board entered into agreement with the Boyce Thompson Arboretum Board and the University of Arizona in 1976 to cooperatively manage the Arboretum.
The University of Arizona also maintains a website for this park, with additional park information and photos. Learn more.
