The Global Lepidoptera Names Index (LepIndex) is a searchable
database maintained by the Department of Entomology at the
Natural History Museum, London. It is based on card indices and scanned journals, nomenclatural catalogues and the Zoological Record. It contains most of world's
Lepidoptera names published until 1981 and for some groups is up to date.[1] As of May 2023[update], the site reads "Database last updated January 2018" so the current validity of the taxonomic combinations presented should be adopted with caution.[2]
