The Peppered Moth: Decline of a Darwinian Disciple. This is the transcript of Michael Majerus' lecture delivered to the British Humanist Association on Darwin Day 2004. The Peppered Moth: The Proof of Darwinian Evolution. This is the transcript of Majerus' lecture given at the European Society for Evolutionary Biology meeting on 23 August 2007.
The peppered moth (Biston betularia) is a temperate species of night-flying moth. [1] It is mostly found in the northern hemisphere in places like Asia, Europe and North America. Peppered moth evolution is an example of population genetics and natural selection. [2] The caterpillars of the peppered moth not only mimic the form but also the ...
Peppered moth insularia on the bark of a lichen-covered birch. By the time of Kettlewell, it was known in England that there were three varieties of peppered moth. The normal, typica, is whitish-grey in colour with dark speckles on the wings. The colour was a perfect camouflage on light-coloured trees covered with lichens.
Antheraea polyphemus, the Polyphemus moth, is a North American member of the family Saturniidae, the giant silk moths. It is a tan-colored moth , with an average wingspan of 15 cm (6 in). The most notable feature of the moth is its large, purplish eyespots on its two hindwings .
The experiments with the peppered moths, as described in this book, are arguably the most dramatic and best known case of adaptive evolution.For many people at that time, this was the first evidence that they could see evolution taking place in the world around them, and could see how fast evolution can go since Darwin came up with the hypothesis (Kettlewell, 1959).
[12] [4] There are visual differences between the migratory and nonmigratory forms of the moth; migratory moths have brown hind wings while nonmigratory moths have paler hind wings. [3] Bogong moths have a wingspan ranging between 40–50 mm (1.6-2.0 in), and a body length of around 25–35 mm (1-1.4 in).
The moths of Lymantria monacha have a wingspan of 40 to 50 mm. They have white forewings with black connected wavy arches which gives the moth its name. The light brown hindwings have white fringes having black spots. They also have a characteristic biscuit-coloured abdomen with a black band. Females are larger and have elongated wings. [1]
Gonimbrasia belina is a species of emperor moth which is native to the warmer parts of southern Africa.Its large edible caterpillar, known as the mopane worm, madora, amacimbi “pigeon moth”, masonja or Seboko sa Mongana, feeds primarily but not exclusively on mopane tree leaves.
