Overview

Cydia leguminana is a moth belonging to the family Tortricidae. The species was first described by Friederike Lienig and Philipp Christoph Zeller in 1846.

The Eastern Piercer (Cydia leguminana) is declining primarily due to habitat loss from agricultural intensification and urbanization of its specialized legume-rich environments. Climate change is altering the phenology of its host plants, disrupting critical breeding cycles, while pesticide use in agricultural areas directly impacts both adult moths and their larval food sources.
