Asian Tramp Snail

Fascinating facts about the Asian Tramp Snail

• A shell no bigger than a fingernail, just 12 to 16 mm across, houses this snail, yet it packs five and a half whorls into that tiny coil. The light-brown shell often bears a single chest-colored band and is etched with fine, irregular growth lines plus delicate spiral striae. The adult's lip is reflected and the columella partly hides the umbilicus.
• Born in Southeast Asia, this snail has become a global hitchhiker, riding on freight containers to appear on distant shores, from the Gulf of Mexico's U.S. states to Florida's gardens, and even on islands like Bermuda, Réunion, Mayotte, Mauritius, New Caledonia, Wallis and Futuna, and French Polynesia. Its habit of roosting on shipping crates makes it arguably one of the most broadly-distributed land snails on Earth, turning ports into accidental launchpads for its spread.
• When it finds a garden, the Asian trampsnail treats every leaf like a buffet, munching on live plant matter such as arugula, citrus, and a surprising range of vegetables. Its appetite extends to coffee rust and even the mycoparasite Lecanicillium lecanii, showing a willingness to eat both crops and fungi. Because it can decimate seedlings and ornamental plants, gardeners label it a pest, and its spread poses a quarantine headache for agricultural authorities, especially in Florida.
• Even a winter dip to 5 °C doesn't freeze this invader out; studies from Louisiana show it can survive temperatures as low as five to ten degrees Celsius. After rain, the snails become active again, seeking shelter under logs or fallen branches in humid, grassy spots.
• Mating for this snail involves a tiny, sharpened love dart, an unexpected weapon in the mollusk world. After courtship, the snail lays eggs that hatch in just two to four weeks. Individuals live two to three years.
