What color and structural features are noted on Great White pupae?
Answer
Pale green or greyish-white, dotted distinctly with yellow and black, and feature ridges with blunt spikes.
The pupal stage provides morphological evidence for species differentiation. The Great White pupae are specifically described as presenting a pale green or greyish-white coloration. Crucially, this chrysalis is dotted distinctly with contrasting colors—yellow and black spots are visible across the surface. Additionally, the structure of the Great White pupa includes ridges that terminate in blunt spikes. This contrasts sharply with the P. rapae pupae, which are variable (brown, mottled-grey, or yellowish) and possess a large head cone but lack the specified spiked ridges and distinct yellow/black dotting of the Great White.
