By habitat

Habitat-associated butterfly species have been defined as those showing ≥ 5% of their total abundance (standardized to 100 m) concentrated in that habitat. However, in the ‘All’ column, the total number of species that have been recorded in the habitat are shown, with no restrictive density threshold. The Butterfly icon shows the species that has been found to be most associated with this habitat. Clicking on the name of the habitat, both in the table and in the graph, you can access the ‘Habitat’ sheet.

The 5% density threshold allows us to see clearly which are the most diverse and the poorest habitats for the Catalan butterfly fauna. Both the Mediterranean and, especially, montane meadows, as well as tall shrubland and the ruderal environments, have a very high number of associated butterfly species. Habitat types including different kinds of forests, alpine meadows and agricultural areas occupy an intermediate position. Coastal habitats, on the other hand, have very low number of associated butterfly species.
