Description
It is a small butterfly with a wingspan of 36 to 46 millimetres (1.4 to 1.8 in). Both sexes look alike, excepting that the male has a prominent brand on the under forewing. It is a plain brown butterfly on the upperside. Underneath, the butterfly is similarly coloured but paler. There are diffused greyish-purple markings on the tip of the under forewing and a series of pale spots in spaces 4 to 9. Similarly spots can be seen on the under hindwing in spaces 2 to 7 and at the end cell.[3][4]
Distribution and status
The butterfly ranges from India to Southeast Asia and the Indonesian archipelago.
India forms the western boundary of the coon with the butterfly found in the Western Ghats in peninsular India, and from Assam to Arunachal Pradesh, other states of the north-east India and into Bangladesh and southern Myanmar.[1][3] In south-east Asia, the coon flies in Thailand, Malaysia, Singapore, northern and southern Vietnam, Laos, Philippines, and possibly southern China.[1] In the Indonesian archipelago, the coon flies in Borneo, Java, Sumatra, Sipora, Bali, Palawan, Sulawesi and Banggai.[1]
The butterfly is common in India.[3]
Subspecies
There are three subspecies:[1]
- P. f. fuligo - found in Thailand, peninsular Malaysia and archipelagos of Indonesia and Philippines
- P. f. subfasciatus (Moore, [1879]) - found in India, Myanmar, Indo-China
- P. f. fuscula (Snellen, 1878) - Sulawesi, Banggai
Natural history
The butterfly is a weak flier which prefers to stay low and frequent shady nooks or grassy patches in forested areas. Often seen perched on leaves. The characteristic identification of this butterfly is that the tips of the forewings remain spread apart even when the wings are closed.[3]
