Last week.

These were in my trap at Philipshill Wood (Bucks) last week, the latter taking a week to identify: A Twin-spotted Quaker with weak spots (f immaculata or thereabouts):

And, in addition to the usual Dyseriocrania subpurpurella, three Eriocrania sangii:

There are a few Eriocrania around just now and they are not invariably subpurpurella, but they can be tricky to recognize.
The nights have not all been conducive to trapping - at least that's my excuse for not going out much, but the days have often been beautiful - as on the day I strolled through Weedon Hill Forestry Commission site and encountered Coleophora laricella larval cases on the Larch trees there:

They betray their presence as much by the feeding damage to the fresh needles, which have been partially hollowed-out:
