They are spread throughout eastern Cuba, particularly within Alexander von Humboldt National Park, which extends from the mountains to the northeastern coast of the island.

[9] Polymita picta mainly feeds on lichen, moss and on fungal biofilms present on bark and leaves.

The life cycle lasts about 15 months, with breeding time during the wet season (September- October).

[10] Like most air-breathing land snails, Polymita picta has female and male reproductive organs (hermaphroditic), it is unable to self-fertilize.

Moreover similarly to other gastropods in the superfamily Helicoidea, this species uses love darts as part of its mating behavior.
