Small Birch Pygmy (Stigmella sakhalinella) mine in birch at Copley meadow, Sept. 9th 2017. I had a pop down to Copley to see the instalment of the bridge at North Dean after the last one was severely damaged by the Boxing day floods. On route I stopped off at Copley meadow and got caught out in a torrential downpour. Whilst sheltering under a birch tree I noticed this mine. Straight away I knew it was something good - the coiled, brown frass throughout was a good pointer. Unheard of in Yorkshire until 2010 it's still quite rare but I suspect more people are now aware of it and searching for it.

Short-barred Pygmy (Stigmella luteella) to actinic light at Norland Bilberry slopes on June 25th 2022. At a mere 2.5mm long this is the smallest moth I have dissected, not the most proficient effort but it was very satisfying when I finally saw the features that clinched a positive ID.
