Studies have shown the New Zealand flatworm to be a predator of earthw
orms and to be widely distributed throughout most of Ireland and Scotl
and. Except for one record in 1965, it had not been found in England u
ntil, in December 1992, it was positively identified from a garden cen
tre near Manchester. Viable and empty egg capsules were also found sug
gesting that it had reproduced and become established in that nursery.
During 1993 other confirmed reports were received from Yorkshire and
East Anglia, indicating that it may be able to survive and multiply ac
ross large areas of England.
