The Garden Zachrysia


The Garden Zachrysia, Zachrysia provisoria (L. Pffeifer, 1858), is a species of land snail commonly found on Sanibel, Captiva, and many other parts of Florida. The species is originally native to Cuba, and is an invasive to Florida, the Bahamas, and several Caribbean islands. Its shell is globose, measuring a tad more than an inch (reaching 30 mm), and is white and translucent, under a brownish “skin-like” periostracum. The aperture lip is white as the rest of the shell, but not covered by the periostracum. The species is considered a pest of garden plants rather than of agricultural crops, as some other introduced species are.
