The Old World swallowtail (Papilio machaon) is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail (a common name applied to all members of the family, but this species is the 'original', first to go by the name). It is the type species of the genus Papilio.

The common brimstone (Gonepteryx rhamni) is a butterfly of the Pieridae family. It lives in Europe, North Africa and Asia. Across much of its range, it is the only species of its genus, and is therefore simply known locally as the brimstone. The name "butterfly" is believed to have originated from the brimstone — which was called the butter-coloured fly by early British naturalists.

The dark clouded yellow (Colias croceus) is a small butterfly of the Pieridae family, that is, the yellows and whites. In India and nearby regions it is known as the dark clouded yellow or common clouded yellow to distinguish it from the other species of clouded yellows occurring there; elsewhere it is often simply known as the clouded yellow, as it was the first and original butterfly to go by this name.

The pale clouded yellow (Colias hyale) is a butterfly of the family Pieridae, that is, the yellows and whites, which is found in most of Europe and large parts of Asia. It is a migrant to the British Isles and Scandinavia.
