Drepanosticta makilingia

Drepanosticta makilingia is a critically endangered damselfly species endemic to the Philippines, specifically known from Mount Makiling in Laguna Province on the island of Luzon. This small aquatic insect belongs to the family Platycnemididae and represents one of several endemic Drepanosticta species found in Philippine mountain ecosystems. The species inhabits forested streams and their immediate riparian zones, requiring clean, flowing water for larval development and adjacent forest cover for adult activities including feeding and reproduction.

Like other members of its genus, D. makilingia likely has a complex life cycle involving aquatic larvae that develop in stream substrates before emerging as terrestrial adults. The species faces severe threats from habitat destruction and degradation, primarily due to deforestation, agricultural expansion, and urban development pressures around Mount Makiling.

Stream pollution and sedimentation from human activities further compromise the water quality essential for larval survival. The species' extremely limited geographic range makes it particularly vulnerable to local environmental changes and human disturbances. Conservation efforts for this species are closely tied to broader forest and watershed protection initiatives around Mount Makiling, which is partially protected as a forest reserve.

However, continued monitoring and targeted conservation measures are needed to prevent extinction, including habitat restoration, water quality protection, and enforcement of existing protected area regulations. The declining population trend indicates that current conservation measures may be insufficient to ensure the species' long-term survival.

This species inhabits forested streams and riparian zones on Mount Makiling in the Philippines, requiring clean flowing water for larval development. Adults depend on adjacent forest cover for feeding and reproductive activities.
