4 days agoWhere to See + Help Track the Thousands of Monarch Butterflies Overwintering in California
Most monarchs live just a few weeks, but the super generation that overwinters in California lives six to nine months. For much of the year, the butterflies are solitary, but they cluster together at overwintering sites, sometimes by the thousands. Monarchs use the groves to rest, but when it's warm enough during the dayabove around 55 degrees Fahrenheitthey break out of those clusters to search for nectar.
