Rare philomela form of Common Wanderer butterfly recorded in Villupuram

A rare philomela form of the Common Wanderer butterfly, Pareronia hippia, has been recorded for the first time in Poothurai, in Tamil Nadu's Villupuram district. The species is more commonly associated with northeastern India and adjoining regions, and records from peninsular India remain scarce, making the sighting near Puducherry an uncommon one.

The butterfly was observed by Smita Rani Mishra, a Puducherry resident, at Matur Udyanam, a unit of the Sri Aurobindo Ashram. The individual was seen resting and fluttering among vegetation on the campus during hot and humid summer conditions.

Mishra said the observation was photographed in the field and later identified as the uncommon philomela form of the Common Wanderer. The butterfly showed the form's distinctive features, including pale yellowish colouration at the base of the wings, translucent whitish areas, prominent dark venation and a faint yellow suffusion near the wing bases. These markings distinguish it from the more commonly encountered forms of the species. The identification was confirmed by noted lepidopterist Isaac Kehimkar, former Director of the Bombay Natural History Society.

A naturalist said the sighting is significant because it provides a record of an uncommon form of Pareronia hippia from the Puducherry-Villupuram-Auroville-Cuddalore (PVAC) bioregion. The observation at Maturudyanam expands the known occurrence of this rare form in southern India, and highlights the ecological value of green spaces maintained by institutions such as the Sri Aurobindo Ashram, which can offer refuge to butterflies and other pollinators.

Systematic observations at Poothurai and across the PVAC landscape could help establish whether the philomela form is only an occasional visitor or part of a little-recorded southern population. The record also reinforces the need to conserve natural and semi-natural vegetation, particularly in rapidly changing peri-urban landscapes across the bioregion that sustain a wide variety of butterflies and other pollinators, Mishra said.
