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?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
