Predators of the peppered moth include flycatchers, nuthatches, and the European robin. Like most moths, peppered moths avoids predators that hunt in daylight by flying at night and resting during the day. Any animal sitting still is harder to see than a moving one.

Industrial melanism is an evolutionary effect prominent in several arthropods, where dark pigmentation (melanism) has evolved in an environment affected by industrial pollution, including sulphur dioxide gas and dark soot deposits.

What would happen if there were no predators in the forest? No they would not change because they already had the genetics to change and they would have no need for camouflage from predators and no need to be darker or light.

Moths evolved long before butterflies; moth fossils have been found that may be 190 million years old. Both types of Lepidoptera are thought to have co-evolved with flowering plants, mainly because most modern species, both as adults and larvae, feed on flowering plants.

16. Dark moths were found in what parts of the country? Near the industrial cities producing pollution. 17.

Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival.১৬ মে, ২০০৫

Dr. Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths.

The answer is yes. Some bats do fly during the day, quite regularly in fact! And, on this island, the insect population can often be 100 times more dense in the daytime hours—an ecological feature that means ‘all day buffet’ for these bats. So, yes, some bats do fly during the day.১৫ অক্টোবর, ২০১৯

The team also found that insects tend to fly higher up, where the wind is fastest. The silver Y noctuid moth, for example, flies 425 metres above ground — higher than the top floor of the Empire State Building in New York.৪ ফেব, ২০১০

Evolution didn’t prevent the moth having a mouth. It allowed the mutation, that involved not having a mouth, to persist, presumably (since it eventually prevailed) because it carried some other benefit, we cannot see without studying it. How come insects evolved six legs while animals and humans only evolved four?
