People also call me Biston Betularia. I resemble a butterfly but have long speckled black and white wings. I am mostly found in the northern hemisphere in places like Asia, Europe, and North America. I mostly live in shrublands, parklands, and deciduous and mixed-wood forests. Stick around to learn more about me.

Many factories have been built and products are produced at a quicker rate. The main fuel source for the factories is coal. The coal releases large amounts of smoke and smog into the environment. ]]> 2022-03-31 18:16:39 UTC https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124140301 Vidhi1 https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124140724 The smoke and smog from the factories are leaving layers of black soot on the trees. Now, everyone else is starting to look more like B because of a mutation in their DNA of the light-colored form. Now, there are two varieties of me!

Can you spot me?]]> 2022-03-31 18:18:33 UTC https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124143411 Vidhi1 https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124144048 The black-colored moths passed their genes down to their offspring and became more successful! ]]> 2022-03-31 18:18:56 UTC https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124144048 Vidhi1 https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124144604 Now, the light-colored moths were easier to see, and were more likely to be eaten by a predator. The dark-colored moths had a higher survival rate and lived longer.

Technology and cleaner-burning fuels started to decrease pollution in the areas where we lived. The lichens started to grow, and the black soot no longer settled on the barks on the trees. As expected, the light-peppered moth became more common in the population. ]]> 2022-03-31 18:19:49 UTC https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124145332 Vidhi1 https://padlet.com/Vidhi1/5zw8td6mzowsvl2n/wish/2124145953 I am on my death bed. I am 364 days old and will pass away tomorrow. Thank You for following me on my journey. Till then, I wish you farewell!
