Recently I was trying to find something amongst some old e-mail (as the other thing I am probably too good at is having a vague recollection of something and then finding it on an old e-mail). Whilst at it, I browsed a few others from the same period and found an old ID request with some completely rubbish photos attached. One of the photos was of an as-then unidentified tortrix from my garden on 13/05/2001 - only looking at it now with over ten years more experience the ID was immediately apparent and I've managed to add a very retrospective tick to the garden list. Checking on the UK Moths archive I then found that actually someone had suggested that ID as well, so no idea how or why I missed the record at the time.
The photo is still rubbish despite the armchair victory!
Fruitlet Mining Tortrix (Pammene rhediella)
There's a slightly better recent photo of one here.
