This kind of data should be collected on multiple places in the world. Given such findings we should thoroughly watch our ecosystems. I have been in Japan during summer this year and (gotten used to the central-European ecosystems where the data for this paper has been collected) was surprised by the amount of insects and especially butterflies, which I had rarely seen for years. Is this just the climate (which also grows some giant insects) or could there be something different at play?
