built 629 days ago

For most of the rainy season, the butterflies of the Pacific coast have a program that says lay your eggs in the same area where you hatched. So, the butterflies live their lives in the same place. At the end of the rains, the females that come out have a different program that says "seek out the rains and lay your eggs there." Off they go to the Atlantic slope and there they will stay until the rain return the following year. Essentially, they are searching for the ideal climate to reproduce themselves.
