Description and Identification
Caterpillar
The journey of the Green-veined White begins with its caterpillar stage. The mature larva sports a vibrant dark green hue, adorned with a faint line on each side running the length of its body. This camouflage enables it to blend seamlessly with foliage, evading predators as it feeds and grows.
Pupa
Transitioning into the pupa stage, the chrysalis mirrors the green of its surroundings, with raised parts accentuated in bright yellowish and brown tones. Following the footsteps of other Pieris species, the Green-veined White overwinters in this form, awaiting the warmth of spring to emerge as an adult butterfly.
Adult Butterfly
Sexual Dimorphism: Subtle yet distinguishable, sexual dimorphism exists in this species. While both sexes display the characteristic green-veined wings, males and females can be told apart by distinct markings on their dorsal wings.

Males feature a single gray spot centrally on their dorsal wings, whereas females flaunt two gray blotches in the same area. The wingtips carry a graceful gray, enhancing their elegance. The underside reveals a soft yellowish-green hue, blending beautifully with their natural habitat.
