Insects are dying at a high rate every year, but it is difficult to estimate an accurate number, because it is a challenge to gather data for millions of species around the world. In a new-to-me series, Reuters broke it down:
The world has lost 5% to 10% of all insect species in the last 150 years — or between 250,000 and 500,000 species, according to a February 2020 study in the journal Biological Conservation. Those losses are continuing, though estimates vary due to patchy data as well as uncertainty over how many insects exist.
