Over most of Africa … The giant African swallowtail is one of the biggest butterflies on the planet.
But females in many localities are conspicuously different from males; their wings lack tails and have colour patterns that vary from… Disruptive Selection Occasionally natural selection favors two extremes, causing alleles for intermediate forms of a trait to become less common in the gene pool. Sister group relationships of the African Mocker Swallowtail, Papilio dardanus, were determined using mitochondrial 16S rRNA and Cytochrome B sequences, and nuclear Elongation Factor EF-la and the ITS-1 region of the ribosomal RNA locus. Females however, show various patterns of black, white and orange, and the color patterns in a particular population are copies of sympathetic species that taste very bad and is rarely preyed upon by birds.

Disruptive selection favors individuals at both extremes of variation: selection is against the middle of the curve. Somewhere beneath the forest canopy was the African giant swallowtail: the largest butterfly to appear by day on the African continent, virtually unrecorded in scientific annals but known to be venomous. Abstract. A species of swallowtail butterfly, Papilio dardanus, is endemic in tropical and Southern Africa.Males have yellow and black wings, with characteristic tails in the second pair of wings. Approximately, 25% of ∼200 Papilio swallowtail butterfly species are mimetic, with independent origins of mimicry in several species groups (Zakharov et al.
Predators have learned to avoid these poisonous butterflies and also to steer away from the look-alike Mocker swallowtails. Pieridae. The African Mocker swallowtail butterfly has undergone this form of selection, known as disruptive selection. Disruptive selection and its effect on a metrical character in the butterfly Papilio dardanus. But females in many localities are conspicuously different from males; their wings lack tails and have colour patterns that vary from… R. I. VANE‐WRIGHT.
