The chrysalis on the left held a developing monarch butterfly. Note the horizontal yellow beads along the upper portion and the pale green marks on the right upper chrysalis. The microscopic image at 40X shows what this area looked like after the butterfly left. The yellow pigment now forms a line across the lower micrograph while three flat, dark openings cross the right central portion of the photo. These are “spiracles” that the developing butterfly used for respiration while it was inside. What an amazing design!
