Here are a few that need ID-ing, I think I am asking alot really with with the amount of detail being shown - but if you don't ask you don't get

.
1. I think this may be a Brimstone - Opisthograptis luteolata, but I have never seen the adult in the garden. Seen in April on the buddleia.
2. There were lots of these over a period of weeks in February, usually eating the crocus foliage or petals, but I do believe they were partial to the polen. when I first saw them they were less than 1cm long but later were about 1.5cm
3. I think this could be a sawfly larva, but wasn't aware they wrapped themselves in silk like this. This was seen in May on the Viburnum Gwenllian.
