Habitat

Lobosculum pustula is found crawling over vegetable debris and among rocky nooks, particularly after rainfall has moisten the ground (Pilsbry, 1940; Bartsch, 1936). Lobosculum pustula along with thirty other land snails crawl the low grounds underneath deciduous trees, vines and orchids (Bartsch, 1936).
