Northern pearly-eye

I was lucky to get this photo. Pearly-eyes usually fly away when approached too closely. Note the black bases to the clubs at the end of the antennae — this distinguishes the Northern from the Southern pearly-eye.

Mystery pearl-eye?

And the antennae on this individual seem ambiguous. They are mostly yellow (as in Southern), but have a slight tinge of dark (as in Northern). Hmm.
