The common flutterer (Leptidea sinapis) belongs to the smaller whites. It has elongated forewings, which have a large dark gray patch in the outer corner. This patch becomes paler or even absent in the butterflies of the second and third generations. The hindwings are entirely white. The underside of the wings is yellowish with a gray speckling.
The common flutterer is a butterfly that can be seen almost everywhere. It flies through forest clearings and along the edges of forests, on shrubby and grassy slopes by the sea, and also above the forest boundary, where it can be seen, although it is rarer there. This delicate butterfly is a poor flyer, and its Slovenian name suits it perfectly. From its weak, fluttering flight you can recognise it already in the air.
