Megalagrion williamsoni
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Megalagrion williamsoni faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited Hawaiian range. Introduced species, particularly non-native fish and invertebrates, compete with and prey upon native damselfly larvae in freshwater streams. Stream modification and water diversion for human use have degraded the pristine aquatic habitats essential for this species' reproduction and survival.
Habitat
This endemic Hawaiian damselfly inhabits pristine freshwater streams and associated riparian vegetation in native forest areas. The species requires clean, flowing water with minimal human disturbance for successful larval development and adult reproduction.
