Observation notes: My husband found it sitting on the walkway at the high school, picked it up, and I placed it in a ceramic bowl. It wasn’t interested in flying away. It laid about 8 eggs in the bowl. I released it near my house and kept the eggs safe. They hatched about 12 days later. I captured 4 of the caterpillars; the rest got away. 3of the 4 perished; developed black spots on their underneath after about 10 days or so. Continued feeding the remaining caterpillar madrone leaves. Just last night (July 31, 2018), he made his cocoon.
