After I'd replied to you, I thought about the damage and thought it
sounded more like caterpillars. Slugs either go for stems, so that you
get wilting branches, or the entire plant is felled, or they make holes
in leaves (like hostas). Disappearance of entire leaves is much more
like caterpillar damage.

Oh, I don't know, I think my dahlias will happily* contest that whole leaf
removal isn't beyond the little buggers. :-(
