Whoa! What Is That in the Houston Floodwaters? Fire Ants Making an Ant Raft.

Their survival mechanisms are amazing.

As if the catastrophic floods in Houston haven’t done enough damage, people are now reporting large colonies of fire ants floating on the rising water.

These fire ants, which are infamous for their painful bites, appear to have an outrageous survival mechanism. And, frankly, it’s unsettling.

Individual fire ants have a slight resistance to water, but that resistance becomes much stronger when they work together. Colonies will link together to stay afloat even in the severe flooding Texas is experiencing.

“They use the wax together on their bodies to keep the queen and other members of the colony in the middle of the ball dry so they don’t suffocate,” Mike Merchant, entomology specialist at the Texas A&M AgriLife Extension Service, told Wired. As they float along, the insects change their positions within the pack to help prevent drowning. 

People are thoroughly disturbed by what Mother Nature hath wrought.

Floating fire ants aren’t a particularly new phenomenon, but that doesn’t make it any less horrifying. 

Have a little mercy, won’t you, Mother Nature?

More MotherJones reporting on Climate Desk


In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones: A special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of the huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
