This weekend we were walking in the Jura, high up enough to be above the line of flowering grasses and therefore cool and comfortable. The flowers were wonderful: purple columbines and strange parasitic yellow broomrapes; odd winged broom pushing up amongst the grass and in the shade of the trees, long spurred butterfly orchids and sturdy white helebores with egg yolk yellow centres, and everywhere there were ants!
The ground was alive with them and every track was a motorway of dark bodies. We found a huge wood ant nest and the surface was crackling with ants. I wondered if this was part of one of the famous super colonies of wood ants that have been studied a little further south in the Swiss Jura. It has been observed that each huge wood ant nest is actually linked to the next nest by tunnels and by lines of kinship. Theses ant cities work together and do not fight each other, creating peaceful and enormously sucessful empires of billions of animal living in harmony.
Not all wood ants live like this, but the colonies in the Jura have been proven to be different. They do not waste energy on fighting their own species, but instead tolerate each other and work together to hunt and forage.
They are hunters of other insects, but one of the bettles they never kill is the rose chafer beetle that was in my last post. If they encounter one of these they push it into the ant hill where it lays its eggs in saftey. These grow into larvea that spend a couple of years with the ants eating the pests that appear in the nest and thus keeping things clean for their hosts, before pupating and flying away.
When humans seem impossible, it would seem that the wise thing to do is to contemplate the even wiser ants!
