A new scientific study challenges the previously accepted estimate of six million insect species by suggesting there could be between 14 and 20 million species globally, more than triple the current figure. The research, published in the Proceedings of the National Academy of Sciences (PNAS), analyzed data from the Guanacaste Conservation Area in Costa Rica—a biodiversity hotspot with extensive inventory records. Scientists sequenced DNA from over 1.6 million tropical insects and identified 54,000 species. To account for undiscovered species, they used parasitic wasps in the Microgastrinae group as a reference, estimating that the area might host around 333,000 insect species. This led to a global extrapolation, resulting in the revised estimate. Researchers emphasized that their findings are conservative, meaning the true number could be even higher.
