Lorquin's lacks the black.  Lorquin's lacks the black.  Lorquin's lacks the black.  I made up this mnemonic a couple years ago when I was trying to remember the difference between these admiral butterflies and the very similar looking California sister.  I've repeated it constantly.  Still, it hasn't really helped me differentiate Lorquin's when they're quickly flying past, so this is my first confirmed sighting.  I'm fairly sure I've seen Lorquin's before but usually guess they're the more common CA sister.  The lacking the black refers to the orange going all the way to the wing tips, without a thick dark border as is found on CA sisters.  Both butterflies tend to be in flight at the same time, too. Apparently, Lorquin's are Batesian mimics of the CA sister.
