Is there no pattern at all to the locations where the greatest decrease happened? If it’s pesticides then the traps nearest an active field of crops will show the greatest decrease. It doesn’t sound like they’re finding that. If it was road deaths then it would be near the roads. If it’s temperature then you would expect to see decreases in hot years, increases in cold years. If crawling insects are affected differently than flying ones, that tells you something. If it’s everywhere at once with no pattern whatsoever, well thats just baffling. It would have to do with the composition of the air or maybe the solar cycle or something else that affects everywhere at once.
