The first monarch butterflies have arrived at their wintering grounds in the forest sanctuaries of the states of Mexico and Michoacán, the National Protected Areas Commission (Conanp) reports.

While the first group arrived “in time” on November 1, 10,000 volunteer observers spread across 18 states including Coahuila, Nuevo León, Tamaulipas, Querétaro and Guanajuato have been reporting that millions of the migrating insects have returned to overnight stops identified last season.

“During this last five days we’ve received reports of large groups of butterflies. The first ones arrived on time to their sanctuaries . . . and we expect that the rest of the traveling groups will arrive within the next three weeks,” Gloria Tavera Alonso told the newspaper Milenio.

The specialist explained that several cold fronts in the Gulf of Mexico may have delayed a few days’ delay for a some of these groups “but they have taken to the skies and thousands and thousands have been seen fluttering through Cuatro Ciénegas, Coahuila; the Monterrey hills, in Nuevo León; in Laguna Madre and the El Cielo biosphere reserve in Tamaulipas.”

Farther south, groups of monarchs seem to be converging as “even larger groups have been spotted in several areas in the state of Guanajuato: Celaya, Salamanca and Xichú, in the Sierra Gorda.”
