Crazy Yellow Ants, Be Gone From This Island

In common language, they are called crazy. They terrorize birds on an island where they did not belong. On this platform we are always going to side with the birds. Full stop. But, even these lousy things ants do are impressive. They remind us that one day ants will rule the planet.

Yellow Crazy Ants, An Enemy To Seabirds, Have Been Wiped Out On A Remote Atoll

The yellow crazy ant was last spotted by Crazy Ant Strike Teams on the vital seabird nesting grounds in December 2017, but it was too soon to tell if they’d been fully extinguished because their colonies are found underground. Robert Peck/HCSU/USGS

After more than a decade, the terrorizing reign of the yellow crazy ant is over on the Johnston Atoll National Wildlife Refuge, part of the Pacific Remote Islands Marine National Monument.

The nonnative invasive insect had been threatening ground-nesting seabirds on the atoll since at least 2010, nearly wiping out the island’s red-tailed tropicbird colony in just a few years and wreaking havoc on other seabirds. But the U.S. Fish and Wildlife Service announced Wednesday that its campaign to eradicate the insects has been a success. Continue reading →

Ant Respect

Common black ant (Lasius niger) workers and three queens.

Any given day in Costa Rica the number of insects one is likely to encounter is too great to count. Ants are not automatically loved, but they are respected. Brooke Jarvis, whose writing we saw primarily in the New Yorker previously, has spectacular photography to accompany her text in this New York Times article in the Science section:

Let Us Now Praise Tiny Ants

Even in the densest human habitations, there are orders of magnitude more ants than there are of us, doing the hard work of making our crumbs disappear.

 

It is telling, the entomologist Eleanor Spicer Rice writes in her introduction to a new book of ant photography by Eduard Florin Niga, that humans looking downward on each other from great heights like to describe the miniaturized people we see below us as looking “like ants.” By this we mean faceless, tiny, swarming: an indecipherable mass stripped of individuality or interest.

Daceton armigerum, male, from northern South America.

Intellectually, though, we can recognize that each scurrying dot is in fact a unique person with a complicated and interconnected life, even if distance appears to wipe away all that diversity and complexity. Continue reading →

Who Invented Agriculture First? It Sure Wasn’t Humans

Ants in Fiji farm plants and fertilize them with their poop. And they’ve been doing this for 3 million years, much longer than humans, who began experimenting with farming about 12,000 years ago. Continue reading →

The Big Headed Ant

Whether it be inside or outside of our homes, ants are everywhere on land. The Pheidole drogon and Pheidole viserion worker ants, found in the rainforests of Papua New Guinea, are ones that have spines protruding from their thoraxes, an intimidating sight for anyone or anything trying to tangle with them. However, researchers suggest that the thorny-looking spine might instead be a muscular support for the ant’s over-sized head, which is used to crush seeds. Continue reading →

Ants & Agriculture

Were Ants the World’s First Farmers?

A new study shows that a group of ants have been conducting a subsistence type of farming since shortly after the dinosaurs died out

By Jackson Landers

Humans have been practicing agriculture for about 10,000 years. But the attine ants of South America (which include the well-known leafcutters) have us beat by a long way.

According to a new paper co-authored by entomologist Ted Schultz, curator of ants at Smithsonian’s National Museum of Natural History, attine ants, which farm on an industrial scale similar to humans, have been carefully cultivating gardens with a complex division of labor to grow an edible fungus. Schultz’s team found that the ants have been doing this far longer than previously believed—up to 65 million years—and that we have much to learn from them. Continue reading →
