A cool spell (around 90 degrees) allowed for a quick trip to Boyce Thompson Arboretum on Sunday. The highlight had to be the huge numbers of butterflies, some of which are shown here.
Ceraunus Blue - there were hundreds, if not thousands of these
Giant Swallowtail - interesting perspective
And another Giant Swallowtail:
There were also several dozen Queen's, some pipevine swallowtails, and western pygmy blue's.
