Zygonychidium gracile

Unknown

Overview

Zygonychidium gracile is a species of dragonfly in the family Libellulidae. It is the only species in the genus Zygonychidium.

Zygonychidium gracile faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited range. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human activities. Pollution from agricultural runoff and invasive plant species further degrade the specialized microhabitats this delicate organism requires for survival.

Threat summary
