There was a recent study of the insect population over a period of time. The study covered a 27 year period in 63 nature protection areas in Germany. While no other areas were studied, the results are very scary. The author concluded that the population declined 76% in that time. He states that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline.
Should we be worried? We've seen the number of bees decline substantially. What else has?
