Because of a coronavirus epidemic European Moth Nights event, originally planned for April 16-20 (2020) has been canceled. We do not want to pose an additional threat to people taking part in the event, so this year we strongly suggest you stay at home. General information about the EMN event can be found here. Detailed information is also provided by EMN ambassadors in individual countries.

Welcome to Lepidoptera Mundi - the online guide to the World’s Butterflies and Moths. It has been created as an extension of the previous version of the website known as European Butterflies and Moths (see the website history).

Lepidoptera Mundi is an open project – everyone can join the contributors team and help the authors to create well-illustrated and easy-to-understand species pages. If would you like to help us - please register yourself and start adding photos and information online.

For historical reasons, the European and Palearctic species are quite well documented. To see all the features of the website, please select Europe or Asia first. The new regions like the Americas, Africa or Australia need your support and are awaiting your help

The website currently contains more than 43k species and subspecies and is continuously extended and updated. To allow you to browse the huge number of taxa, a regions system has been created. It allows you to filter the species list for a specific area, e.g. Africa or North America. You can browse species in four view modes: thumbnails, images, list or tree. You can use also a lot of different tools like advanced search, compare species, UTM map, lunar calendar or record your sightings from any country in the world. It's also possible to create your own gallery and share your photos with other people.
