Rough Hawkbit

Observation - Rough Hawkbit - UK and Ireland. Description: The third image shows a leaf rolled up & 'glued' to form a protective haven for something. Thought I saw something in there but must've moved down to the bottom. Any ideas what species may do this? Any that may be specific to Hawkbits or it's relations
