63 Stigmella lemniscella, mine in Elm, Birdcage Lane, Oct.28th 2010.
63 Stigmella lemniscella, Apr.16th 2011. Reared from mines in Elm found at Bankhouse wood the previous October. Frustratingly this one wouldn't stay still long enough for a decent shot and when they take flight they can easily disappear in to the tiniest of nooks and crannies (or just in to the ether it seems!). It's always a worry that you can easily lose one that you've just spent 6 months rearing.
65 Stigmella speciosa mine on Sycamore by the towpath above Cromwell Bottom, Aug. 10th 2017.
66 Stigmella sorbi, mine and larva in Rowan, North Dean wood, June 22nd 09. Easily told from other mines on Rowan by the initial gallery suddenly widening to a blotch.
66 Stigmella sorbi, Norland Bilberry slopes, Apr.9th 2011.One of two captured by day as they flew in the mid-morning sunshine. Thanks to Harry Beaumont for checking this one out.
68 Stigmella salicis, mine and larva in Sallow, Tag Loop, Oct.16th 09.
70 Stigmella obliquella mine and dead larva on Crack Willow, Elland Bridge, July 18th 2017.
72 Stigmella myrtillella mine on Bilberry at a bridle path at Norland village, Aug. 13th 2017.
I've spent quite a while over the years searching for this miner after Paul Talbot seemed to have had such success in finding mines at several sites within Calderdale. Finally, after a walk up to Norland village on a glorious summer's day yesterday, I came across this one in among the countless, fungal infected Bilberry leaves. As Paul rightly said, it's best searched for on south or south-east facing slopes.
73 Stigmella trimaculella, vacated mine in a poplar species, Park Wood crematorium, July 28th 2010.
77 Stigmella tityrella mine in Beech alongside Ectoedemia argyropeza in Aspen. Taken at Siddal wood on Nov.20th 2016. Two examples of the "green island" effect caused by feeding larvae to keep the leaves edible even after they've fallen.
77 Stigmella tityrella mine in Beech at Kebroyd by the river Ryburn, Oct.16th 2012.
79 Stigmella perpygmaeella, a vacated mine in Hawthorn, New Lane, Sept.23rd 09. The diagnostic yellow larva with a pale brown head was observed under a microscope chewing out an exit hole and vacating the mine. This is the only time I have witnessed this behaviour and also this is my only record.
81 Stigmella hemargyrella, mine and larva in Beech, North Dean wood, June 8th 09. The coiled frass in the middle section of the mine separates it from S.tityrella.
81 Stigmella hemargyrella in Beech by the towpath above Cromwell Bottom LNR, Nov.28th 2016.
84 Stigmella ruficapitella, mines in oak, North Dean wood, July 17th 2010. Eggs laid upperside near the leaf margin.
84 Stigmella ruficapitella (male), Apr.1st 2010. Reared from mines found near Norland village the previous autumn. Similar to other oak feeding stigmellas this one needed to be identified by microscopic examination of the hindwing (see below).
84 Stigmella ruficapitella (male) hindwing, Apr.2nd 2010. The short, dark, thick, hair-like scales (arrowed) are called androconial scales. They are present in the males only and release pheromones so the females can decide with which one to mate with. In this species they are around one third the length of the fringe.
