Despite extensive taxonomic research, the exact size and diversity of global faunas and floras remains largely unknown, with many inventories providing incomplete data.
A study focused on Swedish insects reveals over 3,000 new species, including 301 new to science, showcasing hidden diversity within one of Europe’s most well-documented faunas.
Using three independent methods, researchers estimate that the Swedish insect fauna comprises around 33,000 species, with significant findings indicating that many new species belong to decomposer or parasitoid groups, highlighting taxonomic biases in current knowledge.
