In this post, I showed two little pupa I had found in rolled leaves. The smaller and plainer of the two emerged today.
It is definitely in the same family as the other moth, Tortricidae. The shape of the wings while at rest is quite characteristic, as well as its diminutive size - I did not have a chance to measure it, but I estimate the length from snout to wingtip to be about 4mm. They also have distinctive fringes at the edges of the wings.
So far I'm thinking it's most likely in the genus Acleris.
