Tamil Nadu Sees Annual Migration of Blue Tiger Butterflies to Western Ghats
Tamil Nadu is witnessing its annual butterfly migration as millions of blue tiger and dark blue tiger butterflies travel from the Eastern Ghats to the Western Ghats with the onset of the Northeast Monsoon. This seasonal movement, visible across districts like Coimbatore, Salem, Erode, and Tiruppur, is part of the butterflies' life cycle and ecosystem response to rainfall patterns. The migration also includes species like common and double-branded crows and highlights the importance of conserving butterfly habitats in the region.
