We were delighted to have this Lorquin's Admiral Limenitis lorquini make a visit to our backyard. It fluttered between our Stewartia and the Washington Hawthorne, apparently just basking in the sunshine. The adults sip flower nectar from plants (including California buckeye, yerba santa, and privet) and also enjoy feasting on bird droppings and dung (hmmmm, I wonder if the dairy manure compost we just brought in attracted this one?).
I do not know if any eggs were laid or if this was just a visit; regardless: it was a welcome sight and a relief from all the Cabbage Whites.
Bring on the native butterflies!
