Question of the Week – Sulphur Butterfly Chrysalis

This week, the question was: What is the pinkish-colored thing attached to this tomato stem?

This is the chrysalis of a sulphur butterfly, most likely the cloudless sulphur (Pheobis sennae). The cloudless sulphur is a common butterfly in South Carolina seen frequently foraging wildflowers. The caterpillars feed on legume plants, specifically within the Chamaecrista and Senna genera. The caterpillar in the pupa pictured here likely came from some partridge pea that was growing close by these tomatoes. to learn more about cloudless sulphurs, click here.
