4.002 Drab Birch Pygmy (Stigmella lapponica), mine and larva in Downy Birch, North Dean wood, June 7th 2018. Note the cloudy green frass in the first third of the mine. It then suddenly turns linear and black, presumably coinciding with a change of instar.

Small Birch Pygmy (Stigmella sakhalinella) mine in Silver 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 Silver Birch tree I noticed this mine. Straight away I knew it was something good - the coiled, brown frass throughout is a good pointer. Unheard of in Yorkshire until 2010 it's still quite rare but I suspect more people are aware of it and searching for it.

Eight adults reared from 12 mines that summer was an very good success rate, well, for me at least. At 1.9mm in length this is the smallest moth I've photographed to date......
