[…] What is surprising is how poorly we still understand global ant societies: there is a science-fiction epic going on under our feet, an alien geopolitics being negotiated by the 20 quadrillion ants living on Earth today. It might seem like a familiar story, but the more time I spend with it, the less familiar it seems, and the more I want to resist relying on human analogies. Its characters are strange; its scales hard to conceive. Can we tell the story of global ant societies without simply retelling our own story?

[…] Recognition looks very different for humans and insects. Human society relies on networks of reciprocity and reputation, underpinned by language and culture. Social insects – ants, wasps, bees and termites – rely on chemical badges of identity. In ants, this badge is a blend of waxy compounds that coat the body, keeping the exoskeleton watertight and clean. The chemicals in this waxy blend, and their relative strengths, are genetically determined and variable. This means that a newborn ant can quickly learn to distinguish between nest mates and outsiders as it becomes sensitive to its colony’s unique scent. Insects carrying the right scent are fed, groomed and defended; those with the wrong one are rejected or fought.

[…] It is remarkable how irresistible the language of human warfare and empire can be when trying to describe the global history of ant expansion. Most observers – scientists, journalists, others – seem not to have tried. Human efforts to control ants are regularly described as a war, as is competition between invaders and native ants, and it is easy to see why comparisons are made between the spread of unicolonial ant societies and human colonialism. People have been drawing links between insect and human societies for millennia. But what people see says more about them than about insects.

No moths are harmed for these images thank you have a good evening

A male common darter, from the Netherlands.

I found a large amount of these dragonflies flying around the dunes near the coast. Most of them were found near patches of sand. Here is an example of a log with a few of them standing:

Some of them would stand in the sand and start digging. I also saw some standing while quickly moving their wings. And some of them were mating.

Another thing I noticed is that they were surprisingly unresponsive to disturbances. For example, I would put my camera right to their face and they would not fly away:

Yesterday was very windy and colder than previous days, and so I think maybe these were a bit slow because of the fast drop in temperature and/or being tired from flying in such strong winds. Or maybe they are just too concerned with mating to be worried about my presence.
