Although Lasiommata megera is undergoing a severe decline in central Europe, its trend in Catalonia is stable. At local scale, however, some notable increases have been recorded in the last decades. For instance, in El Cortalet, in Aiguamolls de l’Empordà Natural Park, its population levels are higher today than at the start of monitoring in 1994.

Glaucopsyche melanops is undergoing a severe decline in Catalonia. This negative trend is well reflected in the data from La Conreria, where the population has declined greatly over the past two decades and the species is no longer one of the commonest butterflies as it was in the 1990s. The main reason for this local fall has been habitat encroachment, which has also led to a decline in the main host plants.
