In the dim recesses of my memory I am standing on the baseball diamond of my southern California elementary school as the monarch butterfly migration flutters by. Hundreds of butterflies surrounded us.
Back then no one taught much science in school. Ecology wasn’t a familiar word. DDT was popular.
Yet the wonder of these beautiful orange and black butterflies stopped our gym class game. Even the most nature unaware students stood in awe.
The monarch butterfly migration is moving through the Ozarks now. Those clouds of butterflies have dwindled to one or two a day. And I’ve seen more this year than for several years.
Monarch butterflies are the species shown in science texts as they cycle from egg to caterpillar to pupa to adult. One year we got to watch this for real on the milkweed plants growing around our house and barn.
The adults fly south laying eggs as they go. These adults don’t make it to Mexico. Instead the new generation continues the flight south. A final group makes the last leg of the journey to hibernate.
The monarch butterfly migration is dwindling as those milkweed patches they rely on disappear. Farmers spray their fields and the herbicides drift into ditch rows. Ranchers spray wetlands to increase their pastures. Road crews mow them down. Even conservation department crews mow them down.
People are urged to plant milkweeds. Butterfly weed or purple milkweed are probably the best garden varieties. Common milkweed is spectacular, but it’s tall and tends to spread. Swamp milkweed needs moisture.
There are many other kinds of milkweeds. Most of these are much smaller and their flowers are not as showy. Some require special conditions. Others don’t.
Seeing a monarch butterfly migration was a wonderful experience. Our common milkweed and butterfly weed plants are one way to help such sights happen again.
