(Papilio machaon) a butterfly of the family Papilionidae. The swallowtail is yellow with black markings. Its wingspread reaches 9 cm. It is found in Europe and the temperate regions of Asia and northern Africa, emerging at the beginning of summer and, in southern regions, at the end of summer (the second generation). It winters in the pupal stage. The caterpillar is green with black cross stripes and orange-yellow spots. It develops on plants of the families Umbelliferae and Rutaceae. It feeds on carrots, but damage is usually insignificant.
