Southern California is aflutter thanks to an annual migration of butterflies known as the painted lady. In recent days, the skies of some areas have been filled with the winged creatures.
On the way back, the next generations of butterflies will begin making the trip south. In Calfornia, the largest number of butterflies are expected on the eastern side of the Sierra Nevada, Shapiro said.A similar phenomenon happens in Europe, with some of the butterflies traveling south across the Sahara in Africa and others to Ethiopia and Eritrea, and then the migration begins north across the Mediterranean.
The size of the northern migrations are often tied to the blooms of wildflowers in the desert, because heavy rains there contribute to the growth of host plants, Shapiro said. Anza-Borrego Desert State ParkOnly a few types of birds actually catch the butterflies on the wing, with most being eaten if they are cold or flying slowly or in mud puddles on the ground, he said. And numbers are on the butterflies' side.
"Yesterday, March 11th, was the anniversary for when the front reached Davis in 2005," Shapiro said."I thought it would be really cute if they arrived the same date this time, but it didn’t happen."
