Ants in the Hood
Gathering ants in the city is a curious way to pass a few hours. I can’t say I’d ever given a thought to ant gathering. But on a mild mid-October day, I joined biologists Holly Menninger and Amy Savage, in a green island in the middle of Broadway to look for, and collect, ants.
I tend to look up and out when I walk, alert to the presence of urban birds and mammals like squirrels or raccoons. I scan trees, the sky, water towers, building ledges, the Riverside Park retaining wall. Seeking ants turned my gaze downward to the earth, and focused it narrowly on small patches of ground. My abilities as an ant collector are, to put it gently, undeveloped, but my few hours spent looking for ants has yielded an expanded appreciation for how much life is unfolding in small patches of ground beneath my feet. In a sense, my neighborhood has expanded.
But back to ant collecting.
Holly Menninger is an entomologist and Director of Public Science at Your Wild Life, a team of scientists interested in “exploring the ecological frontiers that exist right under our noses, from the surface of our skin to our backyards and neighborhoods.” Based at the University of North Carolina in Raleigh, Your Wild Life conducts a variety of research projects.
I first saw Holly at the Arnot Forest in Ithaca, NY a little over a year ago. I was attending NY State Master Naturalist training, and she was one of our lecturers. She gave a lively lecture on invasive species with a particular focus on an invasive marine plant that, transported unknowingly by boat owners, was threatening the waterways. More recently, we met through the internet after Holly had moved to North Carolina when, in preparation for up-coming field trips to New York City, she started following NYC nature blogs, including Out Walking the Dog.
Amy Savage is an ecologist who studies ants and their beneficial relationships with other insects and plants. Her research on ant mutualisms has taken her to Samoa, New Zealand, Australia, Costa Rica, Panama, Washington State as well as New York City.
I was thrilled when I learned that Holly and Amy would be gathering ants in NYC, and not just anywhere in NYC, but in my neighborhood within steps of my front door. Needless to say, I joined them.
Here are a few things I learned about ant collecting that you may not know.
1. On a warm, pleasant day in mid-October, collecting ants is quite an enjoyable activity.
2. Ants are partial to Pecan Sandy cookies, which are considered the gold standard for ant bait.
Apparently, Pecan Sandies have just the amounts of sugar, salt and fat that ants love. Still the cookies Amy and Holly had laid out in the medians did not seem to be attracting ants on this day.
3. Real scientists, like Holly and Amy, suck ants. Let me explain. They use a tool called an aspirator which works through suction.
You breath in through a rubber hose, drawing ants up through a nozzle at the other end into the clear collecting jar at the center of the contraption. You are protected from the bits of soil, and other debris that come with the little guys by rubber gaskets that seal off the plastic chamber. Even so, Amy wasn’t too happy on an earlier trip to Broadway medians when she learned that pesticide, said to be rat poison, had been sprayed on plants in the median. (She was even less happy when a rat fell to her feet from a tree while she was collecting.)
4. Faux scientists, scientists-for-a-day, like me, are guided away from the breath-activated aspirator to an electric aspirator. This operates by means of a simple switch rather than human breath. Yet even this very simple machine takes a little time to figure out how to use effectively. I’d spot an ant or two, aim my aspirator and then jab my thumb around in a futile attempt to find the on-button without losing sight of the tiny, well-camouflaged ants. In these early stages of my ant-collecting apprenticeship, quite a few ants escaped my scientific grasp, disappearing into grass or soil before I could get my machine working.
Sometimes the way to get the ants is a gentle and judicious use of tweezers.
We spotted other small creatures, as we searched. Snails, for example, and lots of roly polies, or pill bugs. Roly polies belong to the family of wood louse known as armadillididae, which roll up into tight little balls when threatened. This marvelous rolling-up behavior is given the equally marvelous name of “conglobation.”
Here is another collection of animals, found on the underside of a rock, that include roly polies and other creatures I do not know.
A bright orange spider.
A millipede.
And aphids.
We shared the median with members of our own species as well.
Amy and Holly were indefatigable.
But after a couple of hours, I said good-bye to return to my work.
Later in the day, Holly and Amy apparently hit the ant bonanza in Riverside Park, where ants were plentiful. The next day, they were joined in Morningside Park by Georgia, who writes NYC’s Local Ecologist blog.
Now they’re back in North Carolina, where the ants will be categorized and their DNA will be analyzed.
In a future post, I’ll tell you why these scientists are studying NYC ants, what they’re hoping to learn, and how you can contribute to their research as a citizen scientist.

Wonderful post! Thanks for sharing your “field work” experiences with your readers. You were a HUGE help – We look forward to returning to NYC and seeing you in 2013!

Thanks, Holly! I look forward to the next adventure.

reminds me of a proverb from the bible “consider the ways of the ant”… I remember as a little boy even prior to reading that I was always fascinated by ants… especially how strong they are to move things many times their body weight.

I didn’t know that proverb, Andre. Thanks for sharing it. The strength of ants is phenomenal, isn’t it? In August, I posted a photo of an ant lugging a firefly carcass around – amazing! Here it is: Home from Dallas, Celebrating New York

School of Ants. We humans need more eyes. This sounds like it was a blast, or whatever an explosive intake of air is called.

It was, indeed, an explosive intake of air, Matthew! More to follow.

Well Citizen Scientist, we look forward to the next installment. Love that word – “conglobation”. Bet there is a whole raft of stuff on ant mutualism.
December 17, 2012 at 12:17 pm
It’s a grand word, and how often does the average person have an opportunity to use it? Time to research conglobation.
December 18, 2012 at 3:32 am
Yes, it’s wonderful when we non-scientific folks have chance to get involved … :) It kind of conjures up images, those rolly-pollies and the conglobationing…. !

What a fabulous post! Informative and surprising for someone who knows nothing about insect gathering– millipedes and aphids in the middle of Broadway, and the great name of “armadillididae” (makes me wonder if armadillos roll up too?), what a treat. Can’t wait for part II. Thank you owtd for your scientific citizenry.

Thanks, Charlotte. And, yes, there is at least one species of armadillo (not the one we have in Texas) that rolls up in a ball when threatened. Hedgehogs and echidnas also roll up. Fascinating example of convergent evolution, when unrelated animals (pill bugs and armadillos) evolve a similar trait or behavior. I’m telling you, this science stuff just draws a person on and on … The more you learn, the more there is to find out!
