Where have all the Insects gone ?

The first sensible ,well thought out reply.
The insect mortality on a car windscreen was always a good indicator of their abundance,particularly in gourgeouly hot summer long summer days.
Their varied absence this summer has been quite clear, for those with eyes to see....without them the songbirds will also die,and the lack of a full throttle Dawn Chorus in many areas of Britain now is worrying..not just for those into wildlife...even the posters who see fit to make silly jokes on this thread should be worried....oops I've slipped into scaremongering.
I fly fish and insects are a trouts natural food. The decline in upwing flies (Ephemeroptera) such as mayflies, olives and march brown have been in decline for a long time. When you fish the same waters, at the same time of year, the decline is very obvious.
 

Plenty of research has been done into it and for considerable time too.
Correct. And yet the document also lists a number of limitations to the collected data, insinuating itself that the data cannot be used as irrefutable proof as of yet. If anything, the post notes are hedging almost every ‘fact’ the document claims. In other words, they ‘believe’ numbers have declined, but cannot prove anything until more research has been done.

Thanks for that input,I had a good idea a fisherman would have something to say on the subject.
I have a great interest in the birds and mammal species of the British isles. The Eurasion Cuckoo,a bird which predominantly hunts insects is no longer a common visitor to our shores...This is a mighty sign that insect numbers are not what they were .
It's ten years since I've seen one,and probably 6 years since I've heard one.I conduct my own studies and.....can join the dots.

Something ..is not quite right here.

And it's very worrying,in my opinion.

I wouldn’t go that far with it, there’s enough there to justify a statement that there’s been a decline, it’s quantifying by how much exactly that the data can’t do irrefutably.

The agricultural chemical we use on fields all ends up in the rivers. How the insects are meant to survive is beyond me.
Edit: and sewage accidentally (cough) discharged into rivers.
 
The earth electro magnetic field is being shifted by ever increasing levels of wireless technology, filling the air,the earth and presently the sea.Many organisms,including insects,are reliant on the earth magnetic field for navigation and get disoriented by man made frequencies.

Dr Ulrich Warnke comments in a report:

"All magnetic field sensitivity in living organisms,including fishes,is the result of a highly evolved,finely tuned sensory system based on single domain,ferro- magnetic crystals.Animals that depend on the natural electrical ,magnetic, and electromagnetic fields for their orientation and navigation through earths atmosphere are confused by the much stronger and constantly changing artificial fields created by technology...and fail to navigate back to their home environments"

It’s multiple reasons I think. Habitat destruction, farming, climate, pollution, replacement of native plants and trees with non native. As you say, the impact is felt all the way up the food chain. Insectivorous bird populations in the Uk have nearly all crashed.
