Argyresthia glabratella

This species is undoubtedly under recorded but the larval feeding signs can currently be found on Norway Spruce Picea abies. Look for twigs that have lost the needles from the end (some dead needles may be retained at the tip). Then look for a small circular hole in the twig, usually on the underside. The larva pupates within the twig so if you keep it, you should get an adult in June.
