Yellow Butterfly - Pieris marginalis

Yellow Butterfly - Pieris marginalis
Between Renton/Kent, King County, Washington, USA
September 2, 2013
Looks similar but small to the typical white butterflies I see. Could not get shot of wing backs, so unclear if any markings were present but undersides appear to be unmarked except for variation in the amount of yellow present.

Moved from ID Request.
