The New Zealand flatworm is not native to the United Kingdom. It was first recorded in Belfast (1963) and shortly afterwards in Edinburgh (1965), but is now widely distributed throughout much of Scotland, Northern Ireland and, to a lesser extent, northern England. [more info..]

This website describes the background, objectives and progress of ongoing research investigating the biology and ecology of the New Zealand flatworm in the UK. The work centres on a detailed investigation of specific aspects of A. triangulatus biology identified as critical to the understanding of the establishment and development of populations in new areas, and to the risks posed following introduction into a specified environment.
