You may start to see more and more of a colorful flying insect that’s popular in the Four States.
According to preliminary data, monarch butterflies are having one of their highest population rates in 25 years. The Illinois Butterfly Monitoring Network reports it’s the fourth highest level since 1993.
Researchers don’t know what makes the butterflies have a better year than others, but factors like weather, parasites, and disease could affect the numbers. This data does not reflect the population long-term since it changes from year to year.
The butterflies will travel from the north towards Chicago in the next couple weeks then head south toward Mexico for their final stop.
