Large White Butterfly | Pieris brassicae PUPAE
Pieris brassicae, commonly known as the Large White or Cabbage White, is a widespread butterfly in the Whites & Yellows family, Pieridae. It is native to Europe, Asia, and North Africa but has also been introduced to other regions, including North America. This butterfly is a familiar sight in gardens and agricultural areas, known for its association with cruciferous plants such as cabbages, broccoli, and mustard.
The adult large white is easily recognizable by its white wings with black tips on the forewings and, in females, two prominent black spots. With a wingspan of 5–7 cm, it is one of the larger members of its family. Adults are strong fliers and are often seen nectaring on flowers such as thistles and dandelions.
Females lay clusters of bright yellow eggs on the undersides of host plant leaves. The caterpillars, green with black spots and yellow stripes, are voracious feeders and can cause significant damage to crops. Pupation occurs in an upward-facing chrysalis, which is often attached to fences or walls.
While considered a pest in agriculture, the large white plays an important role in ecosystems as prey for birds and parasitic wasps. Its adaptability has allowed it to thrive, but integrated pest management is often necessary in regions where it impacts crops.
