Eastern San Diego Co.

[Mark Walker]

Eric,

The classification of this checkerspot has been confounded by the use of the
name "Quino".  The butterfly is a sub-species (or race) of chalcedona, and
is principally found in the arid eastern foothills of the Laguna mountains.
It is not a sub-species of E. editha.

I understand that the common name "Quino Checkerspot" has been used for the
sub-species of E. editha that flies in the coastal foothills of Orange and
San Diego Co. (and is currently listed, I believe).  That is not what I saw
in the desert last Friday.  Too bad!
