Abstract
The migratory movements of butterflies are poorly documented in Kerala. It’s for the first time the migratory behaviour of the Dark Cerulean Jamides bochus (Stoll) (Lepidoptera: Lycaenidae) was documented from the Kerala part of Western Ghats. The migratory movement was from high ranges of Eravikulam National Park, Idukki district, Kerala at an elevation of 2085m to the lower elevations in a north-east to south-east direction.
Highlights
As many as six Common Blue Bottles, five Common Crows, five Indian Cabbage Whites and four White Disc Hedge Blues were observed during the count, flying along with the swarms of Dark Cerulean
Except for the Crotalaria spp., none of the larval food plants known for the species—Butea monosperma, Crotalaria spp., Millettia peguensis, Tephrosia candida, Vigna cylindrica, Pongamia pinnata, Xylia xylocarpa (Kunte 2000)—are reported from the Eravikulam NP (Unniyal et al 1998)
The other butterfly species observed during the trek from Vaguvarai to Hut on 12 April 2012 were the Palni

The other butterflies observed along with the migration of Dark Ceruleans were the Common Blue Bottle Graphium sarpedon, Common Crow Euploea core, Indian Cabbage White Pieris canidia and the White-Disc Hedge Blue Celatoxia albidisca. As many as six Common Blue Bottles, five Common Crows, five Indian Cabbage Whites and four White Disc Hedge Blues were observed during the count, flying along with the swarms of Dark Cerulean.
