The Luna or Indian Moon Moth is one of the largest moths in India, with a wingspan of up to 5 inches. Lunas are romantic busybodies at dusk, flying to and from each other with alacrity. They are also prolific silk producers, once common but now more endangered. Scientists believe that Lepidoptera (fancy word for moths and butterflies) are good indicators of the health of a forest. That’s why we grin with glee when we sight them in coffee farms!
