This year (2006) Large Orange Sulphur, Giant Orange Sulphur (Phoebis agarithe) have been blessing our area with their beauty for months. I have never seen so many of them before. In my yard, they especially like to nectar on lantana, pentas, pyramid bush (Melochia tomentosa), cosmos, different types of salvias, portulaca, bougainvilla, rose periwinkle, turk's cap, hibiscus, zinnia, eastern purple coneflower and petunia.
