Satyrium saepium chlorophora
Purplish Hedgerow Hairstreak
This subspecies of Satyrium saepium is somewhat controversial among butterfly enthusiasts. It is said to be darker, often purplish, and a denizen of the coastal parts of San Diego County. The described characters do not always seem to hold, however, and the type locality of "San Diego" is vague. There is more to learn (for me at least) about saepium populations, and whether there are meaningful delineations of different populations in San Diego County. I know I'm not alone in wondering about this.
