The lengthy history of monarch butterflies as a summertime delight in Chicago could end soon.
According to experts, Chicagoans can
help monarch populations by growing milkweed and using fewer pesticides.

The renowned summertime visits of monarch butterflies to Chicago may be endangered due to climate change and extreme weather.
This summer, Chicagoans may have already noticed a decline in the graceful orange and black insects.
A sharp decrease in the number of butterflies before their spring migration has been noticed by researchers in
Mexico. Experts are now concerned that these environmental factors may cause the insect’s well-known migration route to completely disappear.
Since records began in 1993, the quantity of migratory monarch butterflies observed this winter is the
second-lowest amount ever. The pollinator completes the longest known annual insect migration, wintering in
Mexico and California and departing from northern climates in the United States and Canada. The low migratory
numbers of the monarch, the state insect of Illinois, are already a result of threats to the species, including habitat loss and the use of pesticides.
“It would be an inconceivable and terrible tragedy to lose the longest migration path in the world,” Illinois
Environmental Council conservation director Lindsay wrote in an email. “As climate change accelerates, the species
may adapt by shortening the migration path or even staying too long in southern climates where habitat is rapidly declining.”
Experts are concerned about this winter’s notable one-year decline. While annual fluctuations in insect
populations are common, Aster , lead conservation ecologist at the Field Museum’s Keller Science Action Center, expressed concern over this severe
decline. This year’s unusually hot and dry weather, brought on by climate change, was probably to blame.
According to , who goes by “they,” springtime conditions are crucial for this migration because monarchs
mainly rely on environmental cues to determine when to migrate. These migrations are greatly impacted by
shifting climatic patterns, such as variations in the weather and freezing patterns in the southern states.
We will be extremely concerned if the number is extremely low and bad spring weather strikes. In order for the
next generation to survive, we’re all hoping for a wet, flowery spring,” they remarked.
A vulnerable species, according to the International Union for Conservation of Nature, is the monarch butterfly. The
insects were designated as endangered when they were added to the organization’s Red List of Threatened
Species in 2022, but the designation was lowered the following year. The Center for Biological Diversity reports that
monarch populations have dropped by 85% during the previous 20 years.
According to , the decline in monarch populations affects other pollinators. The effects of pesticide use, habitat loss, and extreme weather are also being felt by other insects.
According to a 2019 study that was written up in the journal Biological Conservation, forty percent of insect species face extinction. Pollinators such as bees, wasps, flies, and yes, butterflies,
are essential to food production, so declining populations can have an effect on food supplies, she explained.
spends a lot of his time working to preserve Illinois’s prairie landscapes, of which less than.01% remain. According
to , the environmental council supports regulations that would allow pesticides
and herbicides to be used, but only in a way that is “responsible for the ecosystem and the animals and plants that live in it.”
Planting milkweed, the official wildflower of the state, is one of the best ways citizens can help monarchs. The insects’ primary food source and the
only plant on which they will lay their eggs is milkweed. The city of Chicago’s
Sustainable Backyards Program offers residents up to $90 toward native plants—including milkweed—that can be purchased locally.
suggested volunteering and participating in other restoration projects as a great way to help people who don’t have the space to garden.
Increasing monarch populations in the Midwest can lessen the effects of risk factors that they encounter on their travels.

“Everyone needs to pitch in,” stated . We are creating ecosystems that will be more adaptable to the effects of climate change. And we are able to do that.”view
