Phyllonorycter blancardella or P. hostis? and Cochylimorpha straminea?

 I collected a leaf mine off our apple a couple of days ago. It's now hatched out and I'm thinking it's Phyllonorycter blancardella or P. hostis. It's a bit difficult to photograph the moth in the pot. I'm trying to understand if they can be ID'd from a (better) photo or if they need to be chopped. 

The other query is I think Cochylimorpha straminea.
