Don’t worry. This isn’t an announcement of a new invasion from elsewhere, but a leap into the past in the Paleozoic: the time of giant insects, 100 million years before the dinosaurs, during which insects also had their T-Rex: Carboniferous and Permian giant dragonflies that terrorised the skies of those times, sometimes call “griffenflies”). A short trip back in time to a kind of another Earth in search of insects that were already major actors of the ecosystems.
