Two Pupae and lots of eggs

This fluffy pupa is attached to a dead sprout leaf. I haven't been able to identify it yet; need to do a bit more searching - unless anyone has any ideas? It's about 2cm long (and a little out of focus, sorry).

This brown one was inside the lid of one of our compost bins.
I'm sure it's a small white butterfly pupa.

It's very similar in shape to the one we found in September.

On moving some paving slabs we found masses of eggs. They're either slug or snail - we've had a real problem with our potatoes being slug-damaged this year. After leaving these uncovered for a few days they had all disappeared, so presumably the birds enjoyed chomping them!

 There's a slug in this picture, but I don't think it's actually babysitting!
