Overview

Freyeria trochylus, the grass jewel, is a small butterfly found in Africa, Arabia, southern Europe, India and southern Asia that belongs to the lycaenids or blues family.

The Grass Jewel butterfly faces severe population declines primarily due to habitat loss and degradation from agricultural expansion and urbanization across its range. Climate change is altering the distribution and availability of its host plants, while pesticide use in agricultural areas directly impacts both the butterfly and its larval food sources.
