The swallowtail ( Papilio machaon ) is a butterfly from the family of the knightly butterflies (Papilionidae). The specific epithet is derived from Machaon , a healer from Greek mythology .

description

Wing underside

The swallowtail is next to the sail butterfly one of the largest and most conspicuous butterflies in the German-speaking area and has a wingspan of 50 to 75 millimeters. It is patterned yellow and black with a blue band and red eye-spots on the inner back of the hind wings. Short, mostly black “tails” protrude from the hind wings. He has long hair on his front legs that serve as a cleaning comb.

pairing

The second generation of a year differs from the first by strong colors and yellow-dusted black drawing elements.

The eggs are spherical and creamy white immediately after being laid. Later they turn brown and before the caterpillars hatch they are lead gray.

The caterpillars are about 45 millimeters long and hairless. Initially they are black with orange-red dots and a white saddle point and show bird droppings . The fully grown caterpillars are green in color and have black horizontal stripes with yellow or orange-red dots. A form of the caterpillar occurs that has a white base color instead of the green one.

Subspecies and forms (selection)

Subspecies:

  • P. machaon gorganus Fruhstorfer , 1922, is the subspecies widespread in continental Europe.
  • P. machaon britannicus Seitz , 1907, is a subspecies restricted to England . It is darker than the continental subspecies and shows no migratory behavior . The distribution is limited to swampy areas near Cambridge and Norfolk , where the caterpillar feeds on swamp hairline ( Peucedanum palustre ).

To form:

  • P. machaon f. niger (Reuti 1898), a very rare form with dark brown to black wings on both sides with blue moon spots.
  • P. machaon f. nigrofasciata (Rothke), rare form in which the yellow marginal moons on the hind wings are missing.
  • P. machaon f. aurantiaca (Speyer), shape with strong yellow to orange-yellow wing color

habitat

Papilio machaon lives in one to three generations in sunny and open terrain, such as B. lean grassland and dry grassland . It is only found sporadically on arable land, especially in gardens when carrots , dill and fennel are grown there. The vertical distribution ranges from sea level to the mountains to an altitude of 2000 meters.

Way of life

The eggs are laid on the leaves of the forage plant near the ground. The moths particularly prefer isolated forage plants that stand over open ground and that they can fly directly to.

The caterpillars can be found sporadically on umbellifers ( wild and garden carrots , fennel , dill , parsnip , meadow silge , mountain hairline, etc.), but also on other plants with the same chemical ingredients such as rue and diptame , often in southern Europe the leaves of the citrus plants ( Citrus ). If the caterpillars feel threatened, they turn out an orange-colored neck fork ( osmaterium ) that secretes a scented substance. This defends z. B. ants . If the repeated everting of the neck fork was unsuccessful, the caterpillars flee.

Doll

The caterpillars pupate into green or brown-gray belt pupae. With simultaneous development, pupae rest for 12–19 days in spring and summer, depending on the weather. Caterpillars that pupate in Rhineland-Palatinate from mid-August, i.e. when the day is less than 15 hours, insert a diapause and overwinter as a pupa.

The imagines are known for their hill-topping known (hilltopping) in the spring. At striking elevations such as hills, mountain tops or castle ruins, they sail down the slope again and again in search of sexual partners. In parts of their range, the moths migrate and thus, depending on the climatic conditions, at least temporarily open up new habitats.

Flight time

The first generation flies in Central Europe from April to June, depending on the local climate, the second in July and August and a third in September, depending on the region. Ebert gives the ratio of the adults of the three generations to be 2: 4: 1 for Baden-Württemberg.

distribution

The range of the swallowtail extends over large parts of the northern hemisphere from Europe to Asia and Japan . Several closely related species or subspecies live in North America . The subspecies occurring in Europe - mainly P. machaon gorganus - can be found from North Africa to far north of Europe. In England the species is increasingly rare, however, more frequently in Central Europe. The subspecies P. machaon britannicus , which rarely leaves its biotopes, is restricted to a few swamp areas in England. In contrast, the moths often found on the English south coast between Kent and Dorset belong to the subspecies P. machaon gorganus . They often immigrate from continental Europe and strengthen the local population, which is subject to strong fluctuations, as high losses often occur in winter.

Parasitoids

The swallowtail has various parasitoids , some of which only use the species or genus as hosts. These include:

The caterpillar fly Blondelia nigripes is named as another parasitoid .
