Queenless ant colony trapped in nuclear bunker forever

122864_webKeep calm and carry on building. That’s the motto of 100,000 or so wood ants stranded without food in a nuclear bunker until they starve.

Wood ants (Formica polyctena) typically build a cosy mound nest on the forest floor. They seek out the sugary secretions of aphids living on trees and supplement their diet with insects. Now, scientists have uncovered a population of wood ants that has sustained for years without food and light inside a bunker where temperatures are constantly low.

The ant population was discovered in 2013 by a group of volunteers counting bats overwintering in the bunker, which is part of an abandoned Soviet nuclear base near Templewo in western Poland.

Later, Wojciech Czechowski at the Museum and Institute of Zoology in Warsaw, Poland, and his colleagues, entered the bunker to study the ants more closely. They noticed that the wood ants had built a nest on the terracotta floor of the bunker – right below a ventilation pipe. Looking up through the five-metre-long pipe, they realised where the bunker ants come from.
