[edit] Habitat
The preferred habitat of the adonis blue is calcareous grasslands with hot and dry conditions.
[edit] Species decline
The Adonis Blue has been rapidly declining. This has been due to their habitat (grasslands) disappearing or becoming coarse and shady through a lack of grazing. There are great efforts from conservation organisations and local Biodiversity Action Plans to encourage the populations of chalk-grassland butterflies through managed grazing programs. The recent hot and dry weather associated with climate change seems to be beneficial for this species by making more habitats suitable.
