thank you very much

thanks Lloyd for your interesting ID on this and my other slug photo ( Irish Leopard Slug ). They seem to be somewhat under-represented on Ispot .... it was posted 2 1/2 years ago and your ID is the first !!! Well worth the wait ...

No problem

Your picture looks like Ambigolimax valentianus which was a green house pest in uk and it used to be called Lehmannia valentiana (and still is on iSpot so you can search for it under that name) This slug seems to now be very common in gardens in my area (Dorset), a slight complication is that another greenhouse escapee Ambigolimax nyctelius (used to be Lehmannia nyctelia) which was thought to be similar but with more marked stripes has now been found to occasionally look identical to A. valentianus which makes the specific identification of them tricky.
There is a very nice picture of what I'm sure is Ambigolimax valentianus on the slugwatch website here-
unfortunately I think it has been be misidentified (and misnamed) a Tree Slug Limax marginatus (the tree slug is now Lehmannia marginata!)
Also on this site there is a picture of what I am sure is the Irish Yellow Slug Limacus maculatus
unfortunately I think this has been misidentified and misnamed as the Yellow Slug Limax flavus (the yellow slug is now Limacus flavus)
None of this makes slug identification easy!
