Life Cycle of Queen alexandra's sulphur
Egg The egg stage begins when the female queen alexandra's sulphur lays eggs, usually on a host plant. The eggs are small and may vary in color, often designed to blend with the foliage to avoid predation. The embryo develops inside, preparing to hatch.
Larva Upon hatching, the larva or caterpillar stage of the queen alexandra's sulphur is primarily focused on feeding and growth. The caterpillar may have vibrant stripes or patches for defense, and will molt multiple times, significantly increasing in size after each molt.
Pupal The pupal stage is a time of transformation for the queen alexandra's sulphur, where it develops from a caterpillar into an adult. Encased within a chrysalis, external activity ceases, but internally, dramatic changes occur as the body structure and organs are reorganized.
Adult Emerging from the pupa, the adult queen alexandra's 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 and feeding on nectar.

The eggs are typically found on the underside of host plant leaves. Once hatched, caterpillars feed on these plants and can be found amidst foliage. As larvae prepare to pupate, search on the ground or in lower vegetation for chrysalides, as they often descend to pupate in concealed spots. Finally, adults are generally seen in flight near nectar sources or basking in sunny patches within their alpine and grassland habitats.
