Location: Buena Vista Grasslands
3 2/3 hours. 90-95 degrees F, sunny. This only includes butterflies seen while we walked 3 miles together in the grassland and each walked a different half mile of road edge. We have observed a 55 day Gray Copper flight this year, and probably gained Gray Copper sightings today on 2 forty-acre patches where we hadn't found them before. Butterfly activity dropped off after our 1st hour of surveying, due to the heat and their avoidance of drying out. We saw one female and three male Regal Fritillaries; 3 of Regals were in our 1st survey here, in a plot not usually good for Regals. later surveys in good Regal units found only one Regal, and we think Regals were hiding to avoid drying out. Giant Swallowtail are uncommon here, although we also saw one in 2014.
