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 .

peppered moth, (Biston betularia), species of European moth in the family Geometridae (order Lepidoptera) that has speckled black-and-white wings. It is of significance in exemplifying natural selection through industrial melanism because the population consists of two genetically controlled morphs: one light (very little black spotting) and ...

英文peppered moth，故也译作“椒花蛾” (刘祖洞 《遗传学》 高等教育出版社 1990)或“斑点蛾”。 桦尺蛾在遗传学和 进化生物学 中有着重要的研究意义。 在19世纪中叶之前人们见到的这种蛾，都是浅灰色的翅膀上散布着一些黑色斑点。 1830年左右，英国完成了 工业革命 (Industrial Revolution)，变成了工业化国家， 曼彻斯特 (Manchester)等工业城市的空气污染越来越严重。 1848年，昆虫学家首次在曼彻斯特附近采集到了黑色翅膀的桦尺蛾 标本。 之后，人们采集到 …

2015年8月4日 · Let’s take a look at one animal species that is famous for changing over time to stay camouflaged: the peppered moth. The caterpillar of the peppered moth can blend in on some trees, looking like a twig. Click for more detail. Before the peppered moth is a moth, it's a caterpillar. As a caterpillar, it uses crypsis to avoid being eaten.

Peppered moth, a night-flying moth species of the Geometridae family, occurs in different regions of China, alongside Japan, North Korea, South Korea, India, and parts of North America and Europe. They are called peppered moths because of the unique pattern of their wings, white sprinkled in black or vice-versa.

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced in response to clean air ...

2022年5月23日 · What’s a peppered moth? Biston betularia is a species of night-flying geometrid moth that is widely distributed across the northern hemisphere. Its colour variation, in both the adult and larval stages, has made it an important model organism in evolutionary biology.

2018年5月17日 · The peppered moth (Biston botularia) is an inconspicuous member of the family Geometridae, a night-flying species thought to spend its days resting camouflaged among the lichens that grow on tree trunks. The moth's predominant form has white wings, "peppered" with black specks or faint black lines, perfect for blending in with its tree bark ...

2021年6月9日 · 它们双翅展开约有4-6厘米，翅面上布满了不规则的黑色斑点，看上去就像撒了一片胡椒粉，因而在英文里被称为胡椒蛾（Peppered moth）。 在工业革命之前，桦尺蛾的翅面多为苍白色，当它们停歇在桦树白色的树皮或者树干附生的地衣上时，与环境几乎融为一体。
