Potted plants can seem so benign. Beautiful, fascinating, good to grow and give, but they may carry invasive species which are not benign. Tom Bawden at The Independent tells us about invasive species reaching Europe, including the New Guinea flatworm (Platydemus manokwari) which could be a threat to native snails. Here’s the first report of P. manokwari in Europe.
Mr Bawden tells us about other invasive species which are in Britain, or which could arrive here soon. Those species include:
– the New Zealand flatworm (Arthurdendyus triangulatus or Artioposthia triangulata)
– the harlequin ladybird (Harmonia axyridis)
– the Spanish slug (Arion vulgaris)
– the Asian hornet (Vespa velutina)
– the oak processionary moth (Thaumetopoea processionea)
– the lily beetle (Lilioceris lilii)
– the light brown apple moth (Epiphyas postvittana)
– the rosemary leaf beetle (Chrysolina americana)
– the Argentine ant (Linepithema humile)
Not all alien species are fearsome, of course. In fact living on a set of islands, we British people are used to sharing the land with aliens. And we get on just fine with people in the countries where many of the species we fear are not invasive at all. But sometimes ‘our’ species have become invasive on ‘their’ land. Invasive species are no joke when they invade in any direction.
