when do the monarch butterflies return to mexico
Monarch butterfly migration Starting in September and October, eastern and northeastern populations migrate from southern Canada and the United States to overwintering sites in central Mexico where they arrive around November. They start the return trip in March, arriving around July. No individual butterfly completes the entire round trip; female monarchs lay eggs for the next generation during the northward migration[2] and at least four generations are involved in the annual cycle.
The Very Hungry Caterpillar One Sunday morning, a red-faced caterpillar hatches from an egg, and begins to look for some food. He eats through increasing quantities of fruit on the following five days, one apple on Monday, two pears on Tuesday, three plums on Wednesday, four strawberries on Thursday, and five oranges on Friday, and then, on Saturday, he has an enormous feast with one piece of chocolate cake, one ice-cream cone, one pickle, one slice of Swiss cheese, one slice of salami, one lollipop, one piece of cherry pie, one sausage, one cupcake, and one slice of watermelon. By the end of Saturday, the inevitable happens and the caterpillar gets ill with a stomach ache from over eating too much. On Sunday, he recovers from a stomach-ache and returns to a more sensible diet by eating through a large green leaf before spinning a cocoon in which he remains for the following two weeks. Later, the "big fat caterpillar" emerges as a beautiful butterfly with large, gorgeous, multi-coloured wings.
