Monarch butterflies land on branches at Monarch Grove Sanctuary in Pacific Grove, Calif., on November 10, 2021. The number of western monarch butterflies overwintering in California dropped 30% from the previous year likely due to a wet winter. Researchers with the Xerces Society, a nonprofit environmental organization, said Tuesday, Jan. 30, 2024, that volunteers who visited sites in California and Arizona around Thanksgiving tallied more than 230,000 butterflies, compared to 330,00 in 2022.
