Like bee hives, ant colonies have all sorts of specialized ants. Soldier ants with mighty mandibles guard the hive. The queen ant becomes a gargantuan reproductive machine and pumps out an endless swarm of underlings. Drone ants develop wings to fly high into the air to mate with fledgling queens. Yet the strangest of all ant jobs (to my mind at least) is held by honeypot ants.

Honeypot ants are found in six or seven genera of seasonal ants located in Africa, Australia, Melanesia, and North America. The ants function as living granaries/reservoirs. They find an underground location deep in the hive and use their own bodies as storehouses to protect the hive from drought and famine. As soon as they develop from larvae, the specialized honeypot ants transform into grapelike spheroids capable of ballooning to many time the size of normal ants. During the rainy season, when food is plentiful, worker ants stuff the honeypot ants to the edge of bursting with prey and provender. These living warehouses can store liquids, body fat, and water for long periods in their grotesquely distended abdomens. When the dry season hits and resources become scarce, worker ants stroke the antennae of the honeypot ants and the latter to disgorge their precious stores of liquids and nutrients.

Living deep underground, honeypot ants are seldom seen by people. They were first documented in 1881 by Henry Christopher McCook (a civil war chaplain, polymath, and entomological pioneer). Yet hunter gatherers have known of them since time immemorial. The strange grapelike ants are regarded as a unique delicacy to Australia’s indigenous people who have worked the strange bulbous ants into stories of the dreamtime—the ancient magical creation of the world. Of course the world is not finished and the dreamtime is still ongoing and honeypot ants are out there, engorged in the darkness, doing their part. We just never see them.
