Khon Kaen:The "Common Cassia Butterfly," known for its vibrant yellow wings, is adding a splash of color to the Phu Wiang forest in Khon Kaen province. These butterflies are often seen gathering in large groups by the stream, showcasing their distinctive bright yellow wings.
According to Thai News Agency, the "Common Lemon Emigrant Butterfly," as it is also known, contributes significantly to the vibrancy of the ecosystem in Phu Wiang National Park, Khon Kaen Province. The butterflies' wings vary in color from pale yellow and bright yellow to pale greenish-yellow, with males displaying softer hues and some females featuring striking black markings on the edges of their wings.
These butterflies are especially known for their preference for the leaves of legumes, particularly Cassia fistula and Cassia siamea, during their larval stage. They are a year-round presence, especially visible in the summer months, and are often seen gathering in large groups to absorb minerals from damp soil along stream banks or puddles.
Visitors to Phu Wiang National Park can enjoy the sight of these butterflies while camping or relaxing in nature. Tad Fah Campsite offers a spot for campers until 800 PM, and the Pha Chom Tawan viewpoint provides an opportunity to watch the sunrise from 530 AM.
