Detailed explanation-1: -During September, October, and early November, migratory adults fly to overwintering sites in central Mexico, where they remain from November to March. In March, they begin to journey north, laying the eggs that will become the new Generation 1 along the way.

Detailed explanation-2: -A combination of logging, falling trees, and drought in the areas where the butterflies roost, as well as a reduction of milkweed in their breeding places, pose threats to the monarch’s migration. But the damage wrought by climate change is the biggest factor.

Detailed explanation-3: -Every fall, monarch butterflies fly thousands of miles from as far north as Canada to overwinter in Mexico. When swarms of monarchs pause en route to rest and feed on nectar-bearing plants, admirers will be ready to see them blanket trees and shrubs in orange and black.

Detailed explanation-4: -The large, colorful butterflies known as monarchs are the only butterflies known to have a two-way migration. They begin their migration from the North by late August, depending upon weather patterns. Traveling 10-30 miles an hour, they can cover up to 80 miles in a day. They arrive in Kansas in mid-late September.
