New type of slug/

Hello everybody, long time no talk!
Has anyone noticed a new type of slug which is not nocturnal?
They are about an inch long or smaller and some have orange ridges down the back.They crawl all about on my terrace during the day and the birds leave them alone.I've also noticed a drastic reduction in ordinary slugs when I go out at night with my torch. Could they be a foreign invader?

 

sounds like it could be one of the ones the chap on the link on this thread http://www.gardenerscorner.co.uk/forum/showthread.php?t=18091 talks about lol

 

It's definitely not one of these then - a ghost slug

I have some slugs that eat other slugs - and I've checked them and there is no tiny shell on them and they're an orange colour, they seem to be like a 2 part slug, up at the eating end they're smooth then theres the pooping end thats ridged from front to back (haven't got a clue what type they are though) some have been longer than my finger (scary giant slugs) they're not tiny. Must try to get a picture as I promised on the other slug thread but never have a camera on me when I see them - as long as they leave the plants alone and only eat slugs they can stay in my garden otherwise it's slug busting for them.

 

Now here's how to train those kittens,

LOL Walnut, my cats don't eat slugs :( I've a crow that'll take snails I put on my garden table but it leaves the slugs alone. I've not seen any slugs out and about the last few days - probably the weather keeping them away.
