Having spent some time up at the Kanheri Caves, Limaye was setting off down the Silonda trail with avid trekker and photographer, Naveena Mohan, when he spotted this pair of breeding Atlas moths. The world's largest moth, it is found in tropical and sub-tropical forests across Southeast Asia. When ready to mate, the female releases pheromones which males detect using the chemoreceptors on their antennae. Since these moths are unsteady fliers, the female generally sticks to one spot, picking it based on the air currents to ensure her pheromones are carried far and wide.

The dusty-green caterpillars have fleshy spines covered in a waxy white substance on their backs. They grow to around 115 mm. and then pupate with adult moths emerging after a month.
