A couple of Argyresthias

I believe the first two images are of Argyresthia spinosella, and the second two are of Argyresthis albistria, but I am by no means certain! Do they need dissection to be sure?

Thanks

    Hello Phil,
    Size is quite important in separating Argyresthias but these well-marked ones can usually be done without the need for dissection (it is the all-silvery ones that can cause real identification difficulties!). Assuming that the first pair of images shows one that is at the larger end of the scale then it looks to me like semifusca, but I'd agree that the other is albistria.

    Thanks Dave,
    Size would right for semifusca.
