Common Sailor

The Common Sailor Butterfly (Neptis hylas) is a widely distributed species found across India, Sri Lanka, Nepal, Myanmar, China, and the Indomalayan region. It has over 20 described subspecies.

During the dry season, its upperside is predominantly black with bold white markings. The forewings feature a club-shaped streak and triangular spot, while the hindwings have distinct bands and quadrate spots. The underside ranges from pale to dark ochraceous, with broader white markings bordered in black. In the wet season, the white markings are narrower, and the ground color is darker, with broader black margins.

The larva of the Common Sailor is greenish brown, with spiny processes on specific segments and a slightly pinkish hue. It has a larger head relative to the anterior segment, with short spines on the vertex and obtuse ones on the cheeks. Unique features include an oblique pinkish stripe and a dark lateral spot on one segment. The pupa is compact, with a cleft head-piece, angular thorax, and slightly angled abdominal segments. It is pale brownish-ochreous in color, highlighted by golden thoracic spots.

These seasonal and developmental characteristics showcase the adaptability and intricate beauty of the Common Sailor Butterfly, making it a fascinating subject for study. Found across diverse habitats, this butterfly remains a symbol of the region’s rich biodiversity. Its ability to adjust its appearance based on environmental conditions adds to its ecological significance and allure.
