Really nice pictures, well done. We use very similar gear, so I am encouraged.
I did just think however, that 34 labelled wood white, was in fact a green veined white - you can just see the black markings on the upper wing and the pattern of veins on the lower wing is much bolder than the wood white. I am based near Hereford where there is a wood that is one of the last strongholds of the wood white, so if you need one do let me know.
Keep up the good work, only a few months before we can start again.
