Anthocharis cardamines - Conservation status (Denmark): Least concern (LC) - Lowest risk (Does not qualify for a more at-risk category; widespread and abundant taxa are included in this category)

I have seen it several times in my area in May, just have not been lucky to get it in a photo yet.

Aurora (sommerfugl)

Most of Denmark has aurora butterflies, except in a narrow belt along the Jutland west coast from Hanstholm to Esbjerg.

Orange tip

A. cardamines is mainly found throughout Europe and temperate Asia (Palearctic). The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name.
