Silver-studded blue, a Common card

The card carries these facts from its Wikipedia article.

• It has bright blue wings rimmed in black with white edges and silver spots on its hindwings, lending it its name.
• P. argus can be found across Europe and east across the Palearctic, but it is most often studied in the United Kingdom where the species has experienced a severe decline in population due to habitat loss and fragmentation.
• P. argus engages in mutualism with ants that contribute to the butterflies' reproductive fitness by providing protection from predation and parasitism from the point of egg laying to their emergence as adults.
