Design in the Insect World - Painted Lady Butterflies

We can find some of the most incredible demonstrations of design in the insect world. Survival in places where very cold winters exist presents a challenge for Insects. Some can bury deep underground, but that is not always practical. Another method of avoiding being wiped out by freezing temperatures is migrating to warmer areas for the winter.

The painted lady butterfly (Vanessa cardui) is one of the most common butterfly species in the world. Researchers knew that painted ladies in Europe fly over 9,000 miles (15,000 km) across the Sahara desert to winter in Africa. But, until recently, they didn’t know precisely where these butterflies go. Now scientists have learned that they live and breed in the savannahs and highlands of central Africa.

Painted lady butterflies from Europe spend their time in semiarid savannas from September to November. When those areas become too dry, they head further south to the savannas and highlands across central Africa for December to February. They avoid tropical rainforests because they are too humid for these insects. Like monarch butterflies, they go through multiple generations before the adults journey back to Europe in the spring.

The researchers who studied this incredible migration have learned where the painted lady butterflies go. However, questions remain unanswered. For example, who told these butterflies to make this long journey, and how do succeeding generations know to make the same trip? Most of us in North America are familiar with monarch butterflies and their impressive migration to Mexico. Still, the migration of painted lady butterflies is the longest journey of any butterfly.

God’s design for the survival of all creatures speaks of His wisdom and planning. When we see the design in the insect world, we appreciate the wisdom and power of God, who has entrusted us with protecting all of His creation.

Painted Lady Butterflies Out-migrate Monarchs

Painted Lady Butterflies Out-migrate Monarchs
One of the most amazing things we see in the natural world is the ability of some living things to make incredible migrations. In the past, we have described the monarch butterfly’s migrations from wintering areas in Mexico to northern parts of the United States covering a round trip of about 10,000 kilometers. However, we see that painted lady butterflies out-migrate monarchs.

Scientists have studied how the monarchs navigate such incredible distances with formidable obstacles in their way. Biologists have proposed a variety of models as to how these fragile butterflies could acquire such an ability. However, in the case of the monarchs, the journey is not made by a single butterfly but by a succession of generations.

Science News for July 21, 2018 (page 4) told about a study of another butterfly with an amazing migration. It has the scientific name Vanessa cardui and is commonly known as the painted lady butterfly. These butterflies live in Southern Europe and migrate to Africa in the fall–a distance of 12,000 km. That’s 2000 kilometers farther than the monarchs, and the journey involves crossing the Sahara Desert. As with the monarchs, scientists had believed that the migration involved several generations. New techniques allowed researchers to put markers on the painted ladies when they were caterpillars. We now know that at least some of the butterflies make this incredible journey in one lifetime.

When you look at the barriers to this migration including changes in wind direction, mountains, desert, and storms it is difficult not to be impressed with how the painted lady butterflies out-migrate monarchs. Trying to construct a possible model based on chance processes involves so many assumptions that it is hard to accept that this ability can have an evolutionary explanation. Believing that God’s creation included building a DNA set of instructions that allows the painted ladies and monarchs to migrate is not just an assumption, but the weight of the evidence supports it.
