In November, the butterflies arrive at their hibernation sites and spend several days flying before finding the best place to settle. This is not a good month to visit them so as not to disturb them during their selection process. From December to January, they establish themselves in colonies for hibernation and gather in clusters on tree branches, as the temperature hovers around 0ºC during these months. From February to March, temperatures are higher, and you can observe the butterflies being more active, flying around, mating, drinking water, and feeding on nectar, preparing for their journey back north.

Not every year is the same since there may be variations in temperatures.
