News:

During April and May, these butterflies, generally called ‘tigers and crows’ migrate from the Western Ghat hill ranges towards the Eastern Ghats and plains of Tamil Nadu, before the onset of the southwest monsoon.

As per the reports, large-scale movement could be attributed to good rainfall during the just-concluding southwest monsoon season. Deficit rain during the southwest monsoon and subsequent northeast monsoon until November last year in the breeding areas of ‘tigers and crows’, could have resulted in poor migration in 2023.
