Number of arthropod species detected in the traditional field survey and metabarcoding analysis and their sequence data availability in an expanded database. (A) Comparison of the arthropod species detected using eDNA/eRNA metabarcoding and traditional field surveys (TFSs), and the existence of recently registered species in the expanded database. (B) Comparison of the ratios between species detected in environmental nucleic acids (eNA [eDNA and eRNA]) and TFS and species detected in only TFS.
