Copse snail

Systematic position and biology. The copse snail (Fruticicola fruticum) is a member of the Hygromiidae family within the class Gastropoda. It is a terrestrial air-breathing mollusk recognized by its globular shell, which typically ranges from 20 to 22 mm in diameter and exhibits a brown or yellowish-grey color, often featuring a distinct spiral band. The snail's body is characterized by a grainy texture and a pale, greyish appearance.

Developmental cycle. This species thrives in humid, shaded environments such as thickets, tall grass, and garden beds with dense vegetation. The reproductive cycle involves laying eggs in moist soil or under organic debris. The development from egg to maturity is highly dependent on humidity levels, with the snails preferring cool, damp weather to emerge and feed, while seeking shelter in the soil during dry, hot periods.

Host crops. The copse snail is a polyphagous pest, meaning it feeds on a wide range of botanical hosts. It is particularly problematic in vegetable gardens and orchards, causing damage to lettuce, cabbage, cucumbers, strawberries, raspberries, and various ornamental plants. It is particularly attracted to young, succulent seedlings which are easily consumed by the snails.

Damage and economic impact. Feeding activity occurs mostly at night. The snails use their radula to scrape away plant tissue, resulting in large, irregular holes in leaves and sometimes destruction of the entire plant tissue. High infestation rates lead to significant yield losses, reduced aesthetic value of ornamental plants, and potential transmission of fungal diseases due to the presence of mucus trails on the plant surface.

• Regular weeding to reduce moisture and hiding spots in the garden.
• Installing physical barriers such as crushed eggshells, wood ashes, or coarse sand.
• Using bait traps made of damp cardboard or wooden boards to collect and remove snails.
• Encouraging natural predators such as ground beetles, frogs, and hedgehogs.
• Applying molluscicides containing iron phosphate in severe infestation cases.
