California is experiencing a fabulous Spring! California received rain, wonderful rain to make everything grow.
With that the painted ladies enjoyed a fantastic early season.
Do you remember Wisconsin's Autumn of 2017? We also had painted ladies visit our gardens as they took a break during the migration.
Continue to read on about the current butterfly news happening in California and some Wisconsin butterfly history.
Substantial rainfall in the deserts near the Mexican border, where the North American painted ladies lay their eggs, is the reason for the unusually large swarms. The rain caused plants to thrive, giving the painted lady caterpillars plenty of food to fuel their transformation, said Arthur M. Shapiro, a professor of evolution and ecology at the University of California, Davis.

An unusually wet winter in Southern California has given way to a super bloom of wildflowers and an explosion of Painted Lady butterflies.
The black and orange insects usually keep a low profile as they make their annual migration from the deserts of western Mexico to their breeding grounds in the Pacific Northwest. But this year, they're hard to miss. Scientists say that extra plant growth has allowed their population to boom into the millions.

September of 2017 Wisconsin was blessed with a similar event. Our mild spring weather allowed for an early northward migration. In 2017 Painted Ladies were spotted in Iowa as early as March 10th, which is earlier than normal. With such an early arrival, the butterflies were able to have two generations instead of just one.
For us Wisconsinites, the abundance of butterflies would not be visible to us, because they typically migrate at an elevation several thousand feet in the air to take advantage of favorable wind currents. Using the wind they can travel up to 100 miles a day, and reach speeds of nearly 30 miles per hour. September of 2017, Wisconsin had strong southern weather flow that brought the Painted Ladies down. It is not efficient for a tiny butterfly to try and fly against the wind, so they took a break and were busy refueling on Autumn flowers such as goldenrod, asters, zinnia and sunflowers. It truly was a magical September for Wisconsin and I am sure that is how California folks are feeling this Spring!
