Opération Papillons aims to improve scientific knowledge on butterflies. The data collected over the long term should help measure the effects of human activities on these species.
Participants carry out inventories of butterflies in their gardens or on their balconies, noting the maximum number of individuals seen together for each species. At the end of each week of observation, the data are entered on the observatory website.
This observatory is part of the Vigie Nature network.
Opération Papillons was co-founded in 2006 by the Noé Association and the Muséum national d’histoire naturelle to study butterfly populations and their trends. The project is a citizen science project open to all. No prior knowledge is needed to participate. Butterflies can be observed over one or more weeks depending on your availability. You must then enter the data on the observatory website. You should note only the maximum number of individuals of any species seen simultaneously over one week of observation.Since 2006, data from more than 12,000 gardens have been collected and more than 1,500,000 butterflies have been counted.
