natur&ëmwelt Sektion Haard and Bee Together are organising an event to identify butterflies in the Léiffrächen nature reserve

About this event

L’événement sera en anglais, français, Deutsch et Lëtzebuergesch.

natur&ëmwelt Sektion Haard and Bee Together are organising an event, where, equipped with a net and magnifying glasses, we will identify butterflies in the former open-cast mine known as Léiffrächen, near Kayl. Children will welcome this opportunity to discover our natural world.

For those who are interested, you can use the iNaturalist app on your smartphone to take photos, upload them and use them to identify the butterfly species with help from the guides. See below for what you need to do before the event. As citizens, we can help to increase the data available to scientists by submitting data to the iNaturalist app on our smartphones. We can become Citizen Scientists (1).

iNaturalist is one of the world’s most popular nature apps; it helps you identify the plants and animals around you. Get connected with a community of over a million scientists and naturalists who can help you learn more about nature! What’s more, by recording and sharing your observations, you will create research quality data for scientists working to better understand and protect nature.

Adults and families are invited. Dogs are not invited, as they will scare away the butterflies.

As the activity of butterflies is very weather dependent, the date and time of the event is subject to change. In the case of poor weather conditions, the event will have to be rescheduled.

Register on or before 21 June with Claudine Felten, tel.: 621 38 83 91,

We encourage you to become a member of natur&ëmwelt to support their habitat and nature conservation efforts.  To become a member and to see the benefits of membership, you can consult this link.

We look forward to meeting you.
