Sighting for September 15, 2017

David H. Bartholomew

Del Puerto Canyon
Stanislaus County, CA

With David Rawlinson, John Hibbard, and Nancy Asquith.

Spring flooding scoured the creek bed; most of the buckwheat and milkweed is gone, clover is predominant now. Goldenrod was attractive to blues and hairstreaks.

Acmon Blue females were much smaller than the males, seems like it is usually the other way around.
