Where Have All the Insects Gone? (sciencemag.org)
Entomologists have been assessing diversity and abundance across western Germany and have found that between 1989 and 2013 the biomass of invertebrates caught had fallen by nearly 80 percent. From an article on Science magazine: Scientists have tracked alarming declines in domesticated honey bees, monarch butterflies, and lightning bugs. But few have paid attention to the moths, hover flies, beetles, and countless other insects that buzz and flitter through the warm months. "We have a pretty good track record of ignoring most noncharismatic species," which most insects are, says Joe Nocera, an ecologist at the University of New Brunswick in Canada. [...] A new set of long-term data is coming to light, this time from a dedicated group of mostly amateur entomologists who have tracked insect abundance at more than 100 nature reserves in western Europe since the 1980s. Over that time the group, the Krefeld Entomological Society, has seen the yearly insect catches fluctuate, as expected. But in 2013 they spotted something alarming. When they returned to one of their earliest trapping sites from 1989, the total mass of their catch had fallen by nearly 80%. Perhaps it was a particularly bad year, they thought, so they set up the traps again in 2014. The numbers were just as low. Through more direct comparisons, the group -- which had preserved thousands of samples over 3 decades -- found dramatic declines across more than a dozen other sites. Such losses reverberate up the food chain. "If you're an insect-eating bird living in that area, four-fifths of your food is gone in the last quarter-century, which is staggering," says Dave Goulson, an ecologist at the University of Sussex in the United Kingdom, who is working with the Krefeld group to analyze and publish some of the data. "One almost hopes that it's not representative -- that it's some strange artifact."
It's actually a week-old story, but I only spotted it today. (It wasn't pitched by any reader.) Apologies for running what seems like an old story, but we found it important enough to run it. Thanks.

In other news,:birds eating those missing insects are declining rapidly as well.

This has some scary downstream implications - bird migrations will immediately change, and the ecosystem will have geographic pockets of abundance and scarcity due to that. Food pollination also comes to mind. Corporations do not react to emotional pressures [often] - so any link from pesticide/herbicide usage to lack of pollinators will require a round of market disruption. Even then, the answer may not be insects but something like humans or drones to artificially pollinate sustenance plants until unequivocal proof is found that insects were affect by these chemicals.

You can make broad-brush statements all you want, but:
This was ONE SITE, not the entire country, the EU, or the world.
ONE SITE. You need to know about the ONE SITE because that's where the data lays.
The rest of the sites have had linear and mercurial declines. But the article isn't a broad, or even area-wide statistical analysis. ONE SITE. This is why science journalism gets a bad name.
From TFS, "found dramatic declines across more than a dozen other sites."
Now, maybe my math skills aren't what they once were, but I'm pretty sure that one and a minimum or thirteen are not the same. Perhaps if it's in upper-case it's closer than if it's in lower case.
