Swallowtail

This morning The Swallowtail butterfly was ready to go out.
First he warmed in the morning sunrays.
I had put a blue anemone in his little house and a violet.
He easily stepped on the plant,but I did not see him eating from the nectar.
So I also put inside some nectar for butterflies, not knowing which kind he likes.
He only sat..sometimes moving his wings...fluttering.
