to keep other species out of the main post...
...I'll add down here that the pupa looks very much like the 14-spotted lady beetle's:


There were many empty pupa cases on the willow tree, some of which had definitely belonged to lady beetles (Harmonia axyridis). I thought the small black and white cases were lady beetles too - beneficial species eating the leaf beetle larvae. No such luck...they were probably all leaf beetle pupa cases.
