Population:

Napaeus pruninus is abundant in forested areas throughout São Miguel island. N. pruninusis very variable, the shell and the anatomy resembling sometimes either N. alabastrinus or N. tremulans. It appears also to be some introgression with N. vulgaris, already pointed out by Morelet (1860). The taxon is currently under revision, but here N. pruninus is taken in its current accepted form.

Habitat and Ecology

Napaeus pruninus prefers wooded areas, where it can be found under logs, amidst clumps of dried vegetation, buried in the soil, and sometimes climbing up the branches and leaves.

Major Threat(s):

Although sometimes hard to find, this species is dispersed throughout the island in all types of forests; no threats are foreseen.

Conservation Actions

No conservation measures are needed.
