Egg The yellow angled-sulphur begins as an egg, which is often laid on a host plant. The eggs are small, oval, and bear the distinct coloration which camouflages them from predators. The developmental phase within the egg is preparing the embryo for the larval stage.
Larva Upon hatching, the larva, or caterpillar, is a voracious eater, primarily consuming leaves. The yellow angled-sulphur displays rapid growth, resulting in multiple molts called instars. Each molt sheds the exoskeleton, allowing for larger size, with changes in color patterns for enhanced camouflage.
Pupal After reaching the requisite size, the larva transitions into the pupa. Enclosed within a chrysalis, the yellow angled-sulphur undergoes a radical transformation. The pupal case may exhibit colors that blend with the surrounding environment, providing protection during this vulnerable phase.
Adult Emerging from the chrysalis, the adult yellow angled-sulphur’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. The definitive coloration and patterns are present, facilitating mate attraction and species recognition.
