About Caliphaea sinuofurcata

Common Name: Bearded Bronzeback Damselfly
Taxonomy: Belongs to the genus Caliphaea in the family Calopterygidae, known for broad-winged damselflies. This is only the second species of this genus reported in India, with the first (C. confusa) noted over 165 years ago.

Physical Traits: Exhibits a lustrous, metallic copper-green body accented by olive and yellow tones. Wings are slim and have a faint brown tinge. Dense black bristles around the mouthparts give it a “bearded” look, hence its common name.

The species name “sinuofurcata” is derived from the twisted and forked shape of the male paraprocts, structures used during mating.

Geographical Range:

Native to Arunachal Pradesh, specifically in Upper Siang and Lower Dibang Valley.

Natural Habitat:

Prefers rocky, seasonal streams at altitudes of 1200–1300 meters in mid-elevation broadleaf evergreen forests. The species is typically found in partially sunlit zones with untouched streamside vegetation.

Behavior:

Flies close to the ground and is often seen resting on plants along streams. It avoids human-disturbed environments, signifying its dependence on pristine freshwater ecosystems.

Conservation Concerns:

As a newly described species, it has not yet been evaluated by the IUCN. However, its restricted range and specific habitat needs could make it susceptible to environmental disturbances.
