Distribution

This species occurs throughout the Mariana Archipelago, and has been reported in the greatest densities and population sizes on the isle of Sarigan.^[4]

Ecology

On Sarigan, the species has been recorded most frequently in high-elevation native forests on the trunks of large Erythrina variegata specimens, often resting at the base of branches. On 19 May 2015 specimens were found consuming the Pandanus-fruit ejecta of the Mariana fruit bat on the leaves of a Pandanus tectorius tree. Mariana partulids have been noted to consume plant material, both living and decaying.^[4][5]
