The snails occur only in a single cove. Apparently limestone rock ledges, mature forest affording deep shade, and sufficient moisture are habitat requirements. A. picta was frequently found out on the rock surface or under overhanging slabs of rock. Most land snails are hermaphrodites having both male and female reproductive tracts within a single body. Copulation is commonly preceded by a courtship display.
Fertilization occurs internally and results in the production of jelly-like eggs.
Within its small habitat, the population is thought to be stable, for no one size class predominates. Clearing the forest seems to reduce the available moisture. Crow Creek was channelized in the 1970's resulting, some thought, in a general drawdown of the water table. All the land is in private hands. The owners have been approached by the Nature Conservancy, but have refused to sell or lease their land for a preserve.
