I don´t know anything - but I think, the larva is looking a lot like a Phyllonorycter
... and as far as I know only 2 species of Phyllonorycter feeds on Lonicera
... and the first Phyllonorycter emberizaepenella doesn´t look like your larva - but maybe I am wrong
But the others leaf"mine" - Phyllonorycter trifasciella - is looking a little like yours.
But I don´t know, how the larva is looking of Phyllonorycter trifasciella
- and I don´t know, if Phyllonorycter trifasciella is living in your country.
So you see ... I don´t know anything
