Can anyone identify the attached pic please? JohnnyD

It seems it is Henia vesuviana - so I am not much wiser JohnnyD

Nor I!!  Looks vaguely familiar - but searching its name suggests it is a mainland European species .... so that's another puzzle!

[partisangardener]

I have read it is in the area of Greater London and in coastal areas fairly frequent.

Frodsham is a fair distance from either London or the sea. Unless of course it swam up the Mersey and across Frodsham marshes.

Australian flatworm Australoplana sanguinea came to my garden in potted plant(s) from a nursery, possibly in imported stock.
They established for a decade or so, but now seem to have died out again fortunately.

  Yes, much more likely to have come into the garden via a plant pot.  It's how we got what we called the New Zealand Flatworm and various other pests, animal and plant based    :'(    We no longer have the flatworm, thankfully.
