These are, I think, Phyllonorycter rajella - quite a smart one when freshly emerged and photographed nicely, so here's hoping ....
Upperside and underside of the same leaf. The right hand mine (viewed on the underside) is tenanted
But not sure whether a larva or pupa - it wiggles when gently nudged
Not sure on this one though - a blotch which is evident on the upperside and barely discernible on the underside. There is a live larva in the blotch, again here's hoping ....
Post-script - confirmed as Fenusa dohrnii.
I had a short-lived spurt of enthusiasm for leaf-mines in 2017. After the very hot and sunny spring and early summer, the weather has been a bit crap for nearly three weeks now. The burst of invert overload is all but over, so perhaps leaf-mining is something to generate a bit of interest over the next couple of months.
