Not sure what it is...But I had a similar problem with mine...Although not so severe. Alternated between Pyrethrum & Confidor for a few weeks & it seems to have worked. No Harm in trying. Good Luck

Photos a bit hard to see but looks like Elm leaf beetle damage. Same treatment as for caterpillar - confidor or other pesticide.
Note that you have found a caterpillar? There are likely to be more so keep an eye out over the rest of summer.
