Habitat and Ecology
Acanthinula azorica lives in forested habitats, endemic and secondary, although preferentially on mountainous, endemic vegetation. It is found mainly under decaying leaves. On Pico island, for example, it was found from 150 m to over 1000 m ASL (Martins et al. 2006), and Backhuys (1975) collected it on Flores at about 50 m ASL.

Population

Population
Although found throughout the Azores, it is an uncommon species, found primarily in forests, endemic and secondary. Backhuys (1975) attributes its rarity to the destruction of the mountain, endemic habitat, which the species seems to prefer over the secondary forest.
