Do you know when it bloomed? Usually V.m. 'Sterile' blooms from late March into April, much too early for a Tiger Swallowtail to enjoy it. Also, the leaf doesn't look course enough to be Viburnum macrocephalum.

I have two pictures I've taken that might help. The picture of the bloom with a butterfly is a Hydrangea paniculata taken in August. The other shows a Viburnum macrocephalum 'Sterile' blooming in April. Note how thick and coarsely structured the branches are.
