Highlights: ¡Las Primeras Mariposas Monarcas Han Llegado!

The first monarch butterflies have reached the end of their long migration! Estela Romero announced the news from her hometown of Angangueo, Michoacan, Mexico:

"Yesterday evening (October 30th) I received a phone call from Mr. Germán Medina telling me that the first Monarchs have been seen overflying the Angangueo. They were on their way to 'El Rosario,' which is one of our main Sanctuaries. This morning--and just in this moment (3:08 pm)--the first Monarchs appeared overflying Angangueo's downtown. There are not many, but I can see the first few. It is very surprising that, in only a couple of days, thousands of them are appearing all of a sudden!!!"

News from Northern Mexico
Monarchs are flowing across northern Mexico now. Rocio Treviño is receiving reports from the Mexico/U.S. border all the way to the overwintering region deep in central Mexico:

News From Texas
People who witnessed the spectacular migration along the Texas Gulf Coast last week continued to send in their sightings for the following 10 days. The event is being described by Mike Quinn of Texas Parks and Wildlife as "perhaps the most massive coastal migration in a decade." A cloud of monarchs extended at least 200 miles along the coast, from Houston to Corpus Christi.
  • Here is a series of weather maps that show the conditions at the time.

The first monarchs arrive in Michoacan at the same time every fall, by November 1st. People in the region have noticed this since Prehispanic times. In the language of the native Purépecha Indians, the name for the monarch butterfly is the harvester butterfly, a name given because monarchs appear when it's time to harvest the corn. The Mexican holiday Day of the Dead (Dia de los Muertos) also occurs precisely when the monarchs appear. Traditionally, people believe that the monarchs are the souls of their ancestors, who are returning to Earth for their annual visit.

"On the First of November we remember the souls of our dead children and, on November 2nd, the souls of our adults," explains Estela Romero. "It is also then that the Monarchs traditionally begin to arrive."

Here is a collection of links about the Day of the Dead in Angangueo, and about corn, tortillas, and the growing season in the monarch overwintering area.

Challenge Question #10: Which Sites Do the Monarchs Choose?

Monarchs travel from across eastern North America to a very small region in Mexico as shown on this satellite image. Within the region, only 12 sites have the habitat the butterflies need to survive.

This week's question:

  • Where do you suppose the 12 overwintering sites are? Explain your thinking. What might be special about the places the monarchs choose?

To respond: Write in your journal and send us your answer for possible inclusion in next week's update.
