Q.My Raspberries Have Produced Good Fruit But Many Of The Leaves Have Lots Of Holes Due To Insects. Could You Help Identify Them And

tell me how to prevent them next year? At the start time of the summer there were lots of small white insects flying from leaf to leaf (they are shown in 2 photos). I am wondering if they then turn into the caterpillar (sawfly??) shown. I have been vigilant to remove any of the caterpillars as soon as I spotted leaf holes. Later on in the season little black insects on the underside of the leaves also started to appear underneath some sort of web/cocoon. They appear to be growing into the bigger black grubs shown. I am not sure what they turn into next.
