Monarch Butterfly Migration Route Accidentally Rerouted Through Downtown Chicago After GPS Error

An estimated 40 million monarch butterflies deviated from their traditional migration corridor on Tuesday, passing directly through downtown Chicago in what scientists are tentatively attributing to 'a geomagnetic anomaly' and what the internet is calling 'nature's wrong turn.' The swarm, which typically follows a route through rural Illinois, entered the city from the northwest at approximately 10:30 AM, descending on the Magnificent Mile in a cloud of orange and black that witnesses compared to 'the world's most beautiful locust plague.' 'I walked out of Nordstrom and the sky was butterflies,' said tourist Karen Milkweed of Ohio. 'They were on every surface. The buildings, the cars, my husband. My husband was covered in monarchs and he just stood there because what do you do?' O'Hare International Airport suspended operations for 90 minutes after monarchs entered two engine intakes. The CTA reported delays on the Brown and Red lines due to 'butterfly accumulation on third rails,' a phrase that has never previously appeared in a transit advisory. Entomologists are divided on the cause. 'The monarch's navigational system relies on a combination of solar position, Earth's magnetic field, and circadian rhythm,' explained Dr. Nadine Chrysalis of the Field Museum. 'Something disrupted all three simultaneously. We're looking at solar activity, construction-related magnetic interference, and the possibility that they just wanted to see the Bean.' The migration resumed its normal course by late afternoon. The City of Chicago has declined to pursue damages, with the mayor noting that 'it was objectively spectacular' and that tourism inquiries spiked 300 percent during the event.
