Is There a 1% to 2% Decrease in Terrestrial Insects Per Year?

In Puerto Rico over the last 35 years, there was a 98% decrease in ground insects. There's even a claim that the rate of extinction among insects is eight times faster than that of mammals, birds and reptiles. Some data suggests at least in North America, insect populations aren't really being affected. But overall, it seems like North America has had a relatively stable insect population.
