Colias Gigantea
The reverse design features a portrait of a Colias gigantea drinking nectar from the heart of a wild strawberry flower. The butterfly, engraved and painted inshimmery, light-reflective colour, is viewed in profile from its right side. Standing on one of two strawberry blossoms engraved in exceptional detail, alongside a bud and three leaves from the same plant, thebrightly coloured butterfly characteristically raises its wings as itstands and feeds. Here we are treated to a view of the lovely silver dot on the underside of its wing.
