Southern California ushered in the "Great Migration of Colored Butterflies" Many lands were full of butterflies

According to the American Overseas Chinese Daily Network on March 14, recently, the Southern California of the United States ushered in the annual "color butterfly migration", and many of the land was full of butterflies called the little red butterfly (painted lady).

The butterflies come from the deserts of Mexico, and when they were caterpillars, they fed on desert plants; once they became butterflies, they began to fly north.

It is reported that the first generation of small red butterflies will continue to breed after arriving in Northern California, and then their next generation will continue to travel. After generations of "relays," the insect was able to fly to the northwestern U.S. states of Oregon and Washington.

Arthur M. Shapiro, a professor at the University of California in the United States, said: "The year when wildflowers bloom in large numbers is usually the year when a large number of colored butterflies fly in. The last great migration, he said, was in 2005, when there were billions of butterflies.

Shapiro said he received some reports of the butterfly, such as in Temancura, north of San Diego, Ansappoligo Desert State Park, and in the Pasadena and Kochila Valley.

In California, he said, the number of butterflies expected to appear in the eastern Sierra Nevada is expected to be the highest. "The south has never been as massive as the northern migration," he said. ”
