“…However, for the 10 sequences with abnormal intraspecific genetic distances analyzed in this study, complete specimen information was not retrievable for any of them. Insects have the ability to adjust their morphological and physiological traits to adapt to different environments or host plants, which can result in speciation (Schuh and Schwartz, 2005;Peccoud and Simon, 2010;Ma and Liu, 2020;Li et al, 2021a,b). As a consequence, habitat and host information can be crucial for species identification.…”

“…Collectors typically record geographic information such as coordinates and altitudes in as much detail as possible. Habitat information, including microenvironment and host plant, is also important, particularly for insect collection (Ma and Liu, 2020;Blackman and Eastop, 2021). However, this information is often not well recorded, and therefore can lead to misidentification of species.…”

In recent years, DNA barcoding has rapidly developed as a powerful tool in taxonomy, demonstrating its value in species identification and discovery of cryptic diversity. The number of barcoding sequences of various species continues to grow in the GenBank and BOLD databases; however, the accuracy of sequences and related raw information in public repositories is often questionable. In the present study, based on a dataset of 68,089 Hemiptera COI barcode sequences covering 3,064 species, 1,072 genera, and 48 families, we analyzed genetic differences within and between species and evaluated possible data errors in the insect barcodes. The results showed that errors in the barcode data are not rare, and most of them are due to human errors, such as specimen misidentification, sample confusion, and contamination. A significant portion of these errors can be attributed to inappropriate and imprecise practices in the DNA barcoding workflow. Herein, suggestions are provided to improve the practical operations and workflow of DNA barcoding to reduce human errors.
