Rearing Papilio rutulus
It is somewhat difficult to catch the tiger swallowtails on the wing. Luckily there are a lot of nectar sources here and the butterflies were rather easily nabbed when they were feeding on flowers. There are three broods a year of rutulus at this location. Their favorite nectar sources differs as the season progresses. In the spring it is wild radish and early thistles. In midsummer it is morning glories and sunflowers. In fall it is late thistle, mule fat, and the big yellow flower in this picture. I don't know the name of this flower but it sure was a Godsend.
