Ant Structures With GPS Addresses

Foresters are set to log the ancient Holystone Forest, in Northumberland, England. But first they need to locate and save a few homes located in the forest. Are these structures human dwellings? No, they are giant ant mounds.

The northern, or hairy wood ants  (Formica lugubris) build towering mounds out of pine needles, from three to seven feet tall. The nests act as solar collectors and heaters, allowing wood ants to live in places too cold for most other ants. In addition, the large black and red workers sometimes bask in the sun to warm up and then move underground to act as living heat radiators.

The hairy wood ants that build the mounds are now endangered, and every effort is being to made to protect them. Naturalists located of 69 mounds, which they mapped and gave GPS coordinates. Hopefully, the maps will help the loggers avoid getting too close.

Leafcutter Ant Video

Leafcutter ants are exceptional ants. They construct large, complex nests. Each colony has a number of different worker castes performing a wide variety of tasks. Everything about leafcutter ants is done on a big scale.

Leafcutter ants are named for their habit of cutting out pieces of leaves and carrying the slices back to their nest in their mandibles. Workers process the leaves, spread the resulting paste in an underground garden area, and grow a specific species of fungus on it. Rather than eating the leaves, which may contain toxins, the ants eat the fungus instead. In fact, the fungus is so critical to leafcutter ant survival that the queen ants carry a bit of fungus with them when they go on their mating flights.

This video shows leafcutter ants in action.
