Note:   Plant in shade to attract Zebra Longwings. Zebra Longwing butterflies lay eggs on tender tip growth and tendrils on passionvine growing in the shade or on a very cloudy day.Ants are attracted to passionvine to drink from the nodes at the base of passionvine leaves. If you use a chemical on the soil underneath the plant to kill these ants, butterflies are less apt to lay eggs on the plant. The roots draw up traces of this chemical when the plant is watered. When butterflies come to lay eggs, they taste the un-natural taste of their leaves and may not lay eggs.
