   Jeremy Tatum has two micro moths this morning.  The first one, from a caterpillar raised on Cornus stolonifera, is easy:

    The next one is not so easy, but it was tracked down for me by Libby Avis and Dave Holden as Cnephasia longana, a European invader.  I am sure many viewers have noticed Ox-eye Daisies with the white ray petals folded inwards:
