I don't know why but I'm seeing a lot of anecdotes to support or dispute the linked article. The world is much bigger than any one person's experience, and the data indicates that overall, there are fewer insects. We may have anecdotes that agree or disagree with that statement, but that doesn't disprove the statement or in fact provide any useful content to the discussion.
The real question here is 1. is this a bad sign (magic 8ball says yes) and 2. what can we do about it (this is a deeper question that can't be easily answered because we haven't done in-depth analysis of why these insects have started to disappear, but the suspicion would be that large-scale agricultural and suburban pesticide use is having a much larger and potentially disastrous effect on the earth's ecosystem).
The discussion I'd like to see here is about the ways we can verify this study (trust but verify), determine the source of the problem, and work torwards eliminating that source.
