20 Ectoedemia decentella, on my study window, June 7th 2011. Captured by day and a much sought after species. As the larvae supposedly mine the keys (seeds) of Sycamore I didn't hold out much hope of finding any of the mines so to find this adult with the minimum of effort was most unexpected.
23 Ectoedemia argyropeza tenanted mine in Aspen, found at Siddal wood on Nov.20th 2016. Despite only three Aspens present the mines were quite easy to find.
23 Ectoedemia argyropeza tenanted mine in Aspen, same leaf as above.
25 Ectoedemia intimella, mine and larva on Grey Willow at Tag Loop, Cromwell Bottom LNR, Nov. 13th 2016.
25 Ectoedemia intimella, mine and larva - details as above. Note the mine running along the petiole before entering the leaf blade and also the twin lines of frass.
29 Ectoedemia atricollis, larva and mine in Hawthorn, Bankhouse wood on Aug. 23rd 2017. A typical Ectoedemia mine starting as a narrow gallery, in this case along the edge of the leaf, and then opening out in to a blotch. The dark head of the larva separates it from Stigmella hybnerella.
34 Ectoedemia occultella, mines in Downy Birch, North Dean wood, Oct. 18th 2010. One of the most numerous mines I find. There are around a dozen, tenanted blotch mines on this one leaf alone.
34 Ectoedemia occultella, mine in birch at Tag meadow, Cromwell Bottom LNR, Sept.21st 2017. The frass is concentrated in a blotch, often near the centre of the mine.
34 Ectoedemia occultella (male), North Dean wood, June 8th 09. Captured by day on a Beech trunk. Its identification was aided by advice from Nepticulid expert Erik van Nieukerken and the use of my microscope to examine the forewing scales. Note the eye-caps (scapes) which are modified antennal segments and are a distinctive feature of this family. They are white in the male of this species.
35 Ectoedemia minimella, larvae and mines in Hazel, North Dean wood,Oct.4th 09. Several mines at different stages of development, some tenanted others already vacated.
37 Ectoedemia albifasciella, mine and larva in oak, Siddal wood, Salterhebble, Sept. 9th 2017.
38 Ectoedemia subbimaculella, mine in oak, Bankhouse wood, Nov.26th 2010. The diagnostic "v" shaped slit is just visible against the midrib and vein which allows the frass to escape. This "green island" mine was found on the woodland floor amongst some early snowfall.
40 Bohemannia pulverosella mine on cultivated apple, Skircoat Green allotments, July 3rd 2017. One of at least three mines present.
42 Ectoedemia septembrella, mine in cultivated Hypericum, Skircoat Green, Aug.5th 2012. Having searched far and wide for wild St.John’s-wort I realised it exists in the cultivated form, Hypericum in several gardens close by and it wasn’t long before I found this mine. A nice long, thin gallery abruptly openeing out to a blotch. No adult to rear through this time as this larva had two ectoparasitoids attached!
48 Trifurcula cryptella mine on Common Birdsfoot Trefoil, Tag meadow, Cromwell Bottom, July 2nd 2017. Three mines were found and all were vacated. The gallery frass is greenish/brown, perhaps green when fresh. Eggs and larval exit holes on the underside.
50 Stigmella aurella mines in bramble by the towpath above Cromwell Bottom on Feb. 22nd 2016.
50 Stigmella aurella, mine and larva in bramble, North Loop, Feb.11th 09. Found on a cold, wet, miserable day but the rewards a month later were worth it (see two pics. down).
50 Stigmella aurella, mines and cocoons in bramble, Apr.10th 09. Found in North Dean wood. When rearing stigmellas it's worth checking the leaves after the larvae have vacated the mines to make sure they haven't pupated on them instead of the substrate provided.
50 Stigmella aurella, cocoon and empty pupal case, Mar.11th 09. A fantastic sight which immediately indicated that my first attempt at rearing a Stigmella species had been successful. Reared from the mine above found at North Loop.
50 Stigmella aurella, Mar.11th 09. Emerged from the pupa above. At 3mm long it looks nothing more than a tiny black fly in flight but close-up it has a lovely metallic sheen with a variety of colours.
