Butterflies Luxembourg hosts 19% of all butterfly species in Europe and 6%* of them are considered threatened at the European level. The conservation status of butterflies in Luxembourg based on the European Red List data is relatively good since approximately 90% of the species are classified as Least Concern. However, butterflies have very specific food and habitat requirements at different stages of their life cycle so they are very sensitive to changes in their environment, especially to habitat management such as overgrazing, undergrazing or changes in forestry practices. Status at European level Dragonflies Forty-five percent of all the dragonflies in Europe are present in Luxembourg. In Luxembourg, 2%* of the dragonflies are considered threatened at the European level. This group is adversely affected by desiccation caused by dry weather, fires and increased water extraction for irrigation and human consumption. River species are also affected by ecosystem modifications such as the construction of dams and reservoirs and water quality deterioration caused by agricultural and forestry effluents.

Saproxylic beetles Twelve percent of the beetle species assessed by the European Red List are present in Luxembourg. The conservation status of saproxylic beetles in Luxembourg based on the European Red List data is relatively good since none of them are considered threatened, 6% are classified as Near Threatened and 94% are considered as Least Concern. The species in this group are very dependent on the dynamics of tree aging and wood decay processes. The major threat to this group is logging and wood harvesting; therefore these beetles require sensitive conservation management of tree populations irrespective of their situation. Status at European level Terrestrial molluscs Four percent* of the terrestrial molluscs assessed that are present in Luxembourg are threatened and 7% are Near Threatened at the European level. The major threat to this group at the European level is continuous destruction of suitable habitat from inappropriate ecosystem management, agricultural expansion and livestock farming and ranching.
