Renowned environmentalist Sonam Wangchuk Lepcha took the elusive insect into his possession on October 19, 2025, in the same area where it was first spotted on October 29, 2019. The sighting reinforces Dzongu's rich biodiversity and its position as a critical ecological zone in the Eastern Himalayas.

The Spotless Baron is differentiated from its relatives by the absence of the white spots that give the Baron species its identity. Because of its rare appearances, every confirmed sighting holds great significance for lepidopterists and conservationists.
