Article Synopsis
- 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.
Under an artificial light:dark cycle, females of Lampronia capitella were observed calling, with extended terminal abdominal segments, during the first 2 hr of the photoperiod. Extracts of terminal abdominal segments from females elicited large electroantennographic responses from male antennae. Gas chromatography with electroantennographic detection revealed three active peaks.
