This Hawthorne may be a host for some of those sleeping caterpillars. I did not see the Red-spotted Admiral actually fastening eggs but just maybe (if it is a she) she did.
The only White Admiral form I was able to capture last year was exploring a peony. I am including others from previous years to further illustrate the different forms.
As I write it is snowing outside . . . only passing showers luckily. Snowdrops are taking a stand against the cold and melting snow in their dainty stately way. I guess I can bear up too.
