Fall Means: Monarch Butterfly Migration



Every fall, an interesting and amazing event takes place in the animal world.

The Monarch butterfly travels, sometimes by the hundreds, on an annual migration to Mexico

By instinct alone, the butterflies go to the same mountains that their ancestors left the previous spring.

The interesting part is that they find this place in Mexico without every having been there before.

Monarchs Show Unusual Migration Pattern - Travel WEST!




In an unusual turn of events, monarch roosts appeared last week across western Kansas, and even northwestern Oklahoma and Texas. This is nearly 200 miles west of the pathway the monarchs traditionally travel, based on data collected over the past seven years and shown on the map above.

The monarchs are near the Colorado border, and are already west of the overwintering sites in Mexico. (Notice the location of the overwintering region, at longitude 100 W).

Why are the monarchs so far west?

Did the unusual east winds in the Central Plains over the past few weeks blow them there?

Are they finding suitable habitat in this western landscape, which is typically quite dry? What will happen next?

Will they continue to move westward, or will they drop down straight south into west Texas?

Mountains, deserts, forests, and oceans also influence the monarch's traditional migration pathways. This fall, large numbers of monarchs are migrating where only a few monarchs are usually seen. Something is out of the ordinary!

The Monarch Migration Is Tough . . . Sometimes Impossible



All over the world the Monarch Butterfly soars in the air in the warm climate.

When the cold weather comes in the Monarch Butterfly knows it is time to migrate.

The Monarch Butterfly cannot survive in the cold winter. Each autumn millions of Monarch Butterflies travel over 2,900 kilometers from south Canada to places with warm climates such as Mexico.

But last year there was a major decrease in the population of the Monarch Butterflies that migrate to Mexico from the United States and Canada . Approximately twenty-three million Monarch Butterflies did not make it to Mexico in time. There were less than 75% of Monarch Butterflies in Mexico.

Monarch females can lay several hundred eggs, usually laying a single egg on a plant. The eggs hatch about four days after they are laid

Monarch larvae, like other caterpillars, have very poor vision. They see through six pairs of eyes called ocelli

The Monarch Butterfly is known by scientists as Danaus plexippus, which in Greek
literally means "sleepy transformation." The name, which means to hibernate and metamorphize, is inspired by the Greek myth of Danaus. In this story the daughters of Danaus, king of Libya, escape Libya and go to Greece in order to avoid marrying their cousins. The long migration of the Monarch Butterflies reminds us of the the daughters' flight.

The larvae feed on the plant leaves for about two weeks and develop into caterpillars about 2 inches long.

Monarchs use "thermals," or warm air, to allow them to glide as they migrate. This helps them conserve energy for their long flight. Migrating birds also use thermals.

Monarch Butterfly ~ "milkweed butterfly"


The monarch butterfly is sometimes called the "milkweed butterfly" because its larvae eat the plant. In fact, milkweed is the only thing the larvae can eat!

There are milkweeds growing in the field behind Alcott School and along Walden Street.

If you'd like to attract monarchs to your garden, you can try planting milkweed (if you live in the right area). You can purchase milkweed seed online by clicking on the link in my sidebar below.
[See Caterpillar picture]

Adult female monarchs lay their eggs on the underside of milkweed leaves. These eggs hatch, depending on temperature, in three to twelve days.
