Description

Distribution

This slug is native to Europe, possibly originally only to Greece where it is very common. It is known to occur in a number of countries and islands including:

And also in:

  • New Zealand
  • South America

This species has not yet become established in the USA, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore it has been suggested that this species be given top national quarantine significance in the USA.[2]
