The Death of Insects: What a 75% Decline Really Means
May 27, 2026 · Frisian News
Biomass studies show insect populations have crashed by three quarters since the 1970s, but the science behind the headlines matters more than the shock value. We examined what researchers actually measured and what they did not.
A team of German researchers published findings in 2017 that sent alarm through the environmental press: insect biomass in protected nature reserves had fallen 75 percent in just four decades. The claim spread fast. Journalists ran with the number. Foundations funded new studies to confirm the trend. But look closer at what the data actually showed, and the picture becomes less clear.
The original study tracked insects in nine protected areas in western Germany using nets set in the same spots year after year. The researchers measured total biomass, not species count. This matters because a few large insects can weigh as much as hundreds of small ones. If a reserve lost butterflies and beetles but kept grasshoppers, biomass numbers would still fall sharply. The study told us nothing about whether certain species vanished, only that something got lighter. The researchers themselves noted they did not know which insects disappeared or why.
What the study did not measure matters as much as what it did. It covered nine sites, all in western Germany, all in protected areas, all sampled in summer months only. The findings cannot be stretched to claim insects died everywhere, or that the whole world faces collapse. Yet media outlets and environmental groups did exactly that. They took a local, limited measurement and spun it into a global doomsday story. Foundations now spend millions fighting an insect apocalypse based partly on research that never claimed such a thing.
The real problems with insects do exist. Monoculture farming, pesticides, and habitat loss have hurt populations in some places. But we know less about where, how much, and what to do about it than the headlines suggest. Most insect species remain uncounted. We cannot track a decline in something we never counted to begin with. The alarmism crowds out the harder work of understanding what actually happens on the ground, field by field, region by region.
The 75 percent number became a weapon in the hands of people who wanted to push policies without waiting for better evidence. It sold magazines and brought money to researchers. But it did not solve the real problem. Small farmers who know their land, who see insects in summer and winter, who work with the soil rather than chemicals, these people often know more than the scientists citing the German study. Listen to them first. Then decide what must change.
