Lovely Cabbage White blending in with Blossom

At first glance doesn't this look like an exotic flower with a lot of petals?

That's what I thought at first until I realized that the Cabbage White Pieris rapae was feeding on the nectar.

The butterfly was there for several minutes, and fluttered in the breeze along with the flower.

I have no idea what the flowers are, because a former tenant must have planted it in the plant bed. I think it is a bulb plant that blooms in the early summer.
