Long term sampling from the 1970's to 2017/2018 shows losses of insect, arthropod, and insectivore populations in tropical and European ecosystems. The authors comments were not at all positive about the implications of the population crashes they saw in long term data.
The losses ranged from 75% (1/4 survivorship) to >98% (1/60 survivorship for glue trap samples) from the start of the studies (1970's) until recent census data.
Edited percents.
