An excellent resource for entomologists, this Butterflies and Moths of the World website was created by Brian Pitkin and Paul Jenkins of the Natural History Museum in London (NHM). The site was designed "to compile a comprehensive interactive catalogue of all the published genus-group names of Lepidoptera from Linnaeus, 1758, up to the present, and to provide full-colour images of representatives of most included families." This online catalogue contains 31,147 entries and over 400 full-color images as well. Additionally, a bibliography is included that provides "6,155 references by 1,281 different authors or author combinations." Site visitors can conduct searches for a specific genus, type-species, bibliographical reference, or image. This website also links to other NHM Department of Entomology sites including Research Themes, Publications, and Databases.
