Yes. This is a case of hard data confirming what we already know. As in - few types of butterflies I used to like, and see yearly as a kid - are gone. I see them now once in 5 years, if lucky. I bring my kids to look because it's a first time for them. On the other hand, some types of beetles, ants, flies, mosquitoes, even wasps - are just new. They were not here 20-30 years ago. Now, what are the consequences of all…
I’m seeing a ton of wasps this year too. Also seems like there’s way more spiders in recent years.

I wouldn't jump into blaming the climate. We've shifted many parts of a very complex system in the last 50+ years. I'd put monoculture and pesticides higher on my list of suspects.
As an anecdotal data point, I'm trying to establish a robust, poly-culture, mostly chemical-free agricultural system on my hobby farm. We do seem to get more flying insects on my place than our neighbors, all of whom have grass lawns. Critters of all kinds, in fact - lots of frogs and toads as well, and box turtles. Obviously I haven't done a scientific study, but we see butterflies, lighting bugs, and so on; not as…

That has a simple explanation, though. Monarch caterpillars can only survive on milkweed, and we've decimated the amount of milkweed around because we see it as, well, a weed.
You can help out with this by harvesting seeds and planting them all over!

#74I'm extremely unqualified, but is it possible that the insects just learned to avoid the specific traps used to do the measurements over time?

#75Over the last year, reading the news had made me more passive and worried. I want to dedicate a slice of time to doing something to solve the problem, but I'm not certain if there's anything pragmatic to be done against big areas of environmental concern like this, global warming, ocean acidity, and etc.

This kind of the same thing I'm seeing with firefly in Michigan. In the summer time when I first moved to MI over 30 years ago I use to see them everywhere in large amounts. This year they're back but last 3 years I didn't see them at all. As long as there are climate change deniers a.k.a Trump supports we're all in a lot of trouble, even humans.
Some of the people you go out of your way to slander as both trump supporters and climate change deniers exist as they do because of people like you, who immediately take any adverse global trend, blame it on climate change with what amounts to shakey, correlative evidence, and then shame anyone who dares glance over with a skeptical eye. We are dumping all kinds of chemicals into the environment - pesticides, plasti…

#77Results like this are some confirmation of what everyone not entirely swaddled in the virtual worlds of city and business is already entirely aware of: that our living planet is dying. All the people I know who have lived in rural areas for decades (in Europe, Australia, New Zealand, Indonesia and SE. Asia) are in no doubt that their local ecologies are collapsing, and that the collapse is accelerating. I'm not sure…

This is making the headlines in Germany right now: http://www.zeit.de/wissen/umwelt/2017-10/insektensterben-flu... http://www.spiegel.de/wissenschaft/natur/insekten-in-deutsch... http://www.sueddeutsche.de/wissen/insektensterben-dramatisch... Der Spiegel discusses issues in the methodology of the data collection. The intervals over the years weren't uniform, data was collected by volunteers/hobbyists and they did not…
The massive use of neonicotinoides would not surprise me given the research of its impact on bee colony collapse.
