The great-banded gray butterfly is a species of butterfly belonging to the family of gray butterflies. The wings are greyish brown with distinct streaks and spots, which have a good camouflage effect. Medium-sized, with a wing span of about 45-50mm. It is mainly distributed in central and southern Europe, including southern Germany. Usually inhabiting open grasslands, shrubs and forest margins, the adults feed on nectar. In the face of hot and dry summer, the strategy of summer sleep is adopted to adapt to the environment. The larvae feed mainly on herbaceous plants, while the adults feed on nectar. Population numbers have declined over the past few decades, mainly due to habitat loss and climate change.

Belonging to some small butterfly species in the family Lycaenidae, they are known for their soft gray, white, or brown wings and unique markings. The Grey Butterfly family is one of the largest families of butterflies, widely distributed and diverse worldwide. Larvae mainly feed on the leaves of various plants, while adults feed on nectar. Plays an important role in the ecosystem as a pollinator, promoting plant reproduction, and also serves as a food source for many bird and other insect predators. Eggs are usually laid on the leaves of the host plant. After hatching, larvae begin to feed and undergo several molts before entering the pupal stage, eventually emerging into adults.
