Asiagomphus yayeyamensis

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Asiagomphus yayeyamensis faces severe threats from habitat degradation due to agricultural expansion and urban development across its limited range in the Yaeyama Islands. Water pollution from agricultural runoff and domestic wastewater significantly impacts the pristine stream conditions this dragonfly requires for successful reproduction. Climate change poses an additional threat through altered precipitation patterns and increased storm intensity, which can disrupt the delicate aquatic ecosystems essential for larval development.
