The Hungarian Lepidopterological Society and the Entomological Society of Luzern (Switzerland) organise an annual event called European Moth Nights.
The aim is to gather a wide-ranging snapshot of the macro-moths flying during the period, paying particular attention to migrant species and those in need of conservation.
Participants can submit macro-moth records from any or all of the five nights and from one or many locations. The data should be submitted using Excel templates that have been specifically designed for the event. These can be found at the European Moth Nights website or ordered by post.
The next European Moth Nights event is planned to take place from 11 - 15 July 2013.
