We are suckers for hype. The recent media sequel of the mythical Insect Armageddon and the coverage of the latest WWF report on wildlife declines are a reminder of this.
Global declines in insect populations are a huge concern. Insects contribute to myriad ecosystem services through a multitude of ecological processes and functions. If we lose insects, we WILL suffer. But the two studies media have hyped on this issue are not actually evidence that this happening. They are concerning; they are a wake-up call; they are worrying.
