Diet: Seeds and seedlings of cereal crops, and apple, pear, plum, and peach trees

Habitat: Wrinkled dune snails frequently inhabit dry, open areas such as pastures and coastal plains.

Native Range: Western Europe

Local Concern: This species of snail will damage fruit crops while still attached to the tree, which may allow for secondary infections that can kill the tree. They also have a high propensity to aggregate on cereal grains. This poses a threat of contamination and of secondary infestation by fungal pathogens that make the grain toxic. They are difficult to manage because they are able to survive cultivation in field cropping systems.

Potential Means of Introduction: Several pathways for invasion exist including hitchhiking.
