Low growing bog plants for insects, slugs, etc

[Falesh]

I've just made a bog area about 50cm by 150cm just under a hedge. The garden is going to be well stocked with necter plants so I don't need more of that but what I would like are more things that attract creepy crawlies for the amphibians and birds to much on. I'm going to have a decent amount of wood in one side of the bog to rot down but does anyone have any suggestions for plants in the other side?

I love hostas they are perennial but the slugs and snail really love them too they grow in a bog or water..
be warned you will be left with a pin cushion of a plant also ferns as they provide somewhere for a daytime retreat.

The Hostas look perfect, I'll go with two Gold Standards for plenty of slug salad.
