Lepidoptera Mundi (formerly European Butterflies and Moths)
European Moth Nights is a cyclic event that consists of observing and collecting information about moths (Heterocera, Macrolepidoptera) in the same time period throughout Europe.
Portal Lepidoptera Mundi together with the Department of Invertebrate Zoology and Hydrobiology and Faculty of Biology and Environmental Protection, University of Lodz (Poland) continue the project started in 2004 and initiated by Hungarian and Swiss Entomological Societies.
This year's 20th edition of this event is scheduled on 4-8 July.
Unfortunately, the date of June 15-19 given earlier on the main page was a mistake (the date was in the middle of the week), for which I am VERY sorry.
We count on the help of entomology societies, groups, organizations as well as amateur entomologists who care about biodiversity protection. Each year we have 5 days for carrying out observations. Data can be collected on one or more designated days in one or more places. We encourage you to take part in the initiative and we count on your help.
The records can be added online or offline using a Excel template. The completed Excel sheet should be sent by the deadline of October 31, 2024.
