16th Annual Butterfly Count at Boyce Thompson Arboretum


At Boyce Thompson Arboretum

Saturday, September 10, 2022
8:30 AM - 12:00 PM

On Saturday September 10th we tackle our 16th Annual Butterfly Count. The total count circle has a 15 mile diameter and we will conduct a one-day census of all butterflies sighted within that circle. 80 species of butterflies appear on the Arboretum's checklist, while the record for most species observed in a single day is 44 by Marceline VandeWater during the same count in 2011! Xami Hairstreak is one of specialties that has been found in the past at the BTA. Compiler Dr. Ron Rutowski (rrutowski at cox.net)
