345 Phyllonorycter rajella mine and empty pupal case in Alder. Found near the towpath at Sowerby Bridge, Sept.6th 08. Note the typically prominent central crease to the mine. Sometimes rearing members of this family can be as simple as collecting the mine and placing it in a rearing pot/jam jar and awaiting emergence, sometimes within a day or two.
345 Phyllonorycter rajella , July 5th 2014. Reared from mines on Alder on the towpath near the tip at Sowerby Bridge.
351 Phyllonorycter lautella mine on oak at Norland village on July 14th 2017. The mine was 20mm in length reaching from the mid-rib to the leaf margin. Moth reared.
351 Phyllonorycter lautella, Apr.12th 2011. Reared from a mine on oak found near Norland village on Mar.30th that year. I suspect that there maybe a permanent colony here. A personal favourite of mine for three reasons.
1. It's a beautifully marked moth - unlike most of the other"run of the mill" phyllos.
2. It only took 13 days to rear - no overwintering involved.
3. It was totally unexpected - I was quite convinced it was the much more common P.quercifoliella.
One other record of a moth reared from a mine on oak found a Tag meadow on Dec.14th 2013. The moth emerged on Mar.1st the following year.

356 Phyllonorycter tristrigella, Mar.17th 2010. Reared from mines on Elm found in Bankhouse wood the previous autumn.
358 Less Small Midget (Phyllonorycter froelichiella) mines and larvae in Common Alder by the Calder at Copley village, Oct. 1st 2017. Don't you just love the old English names for micros - shame they're not more widely used. Fairly common this one in Common Alder. Key points are multiple, long mines per leaf with a reddish/brown spot where the side vein meets the mid-rib. Each mine has a larva and frass pile visible.
Phyllonorycter mines are overwintered outside in nylon pockets secured to a numbered, wooden frame for identification purposes.They are then brought indoors around the end of February for the adults to emerge.
358 Phyllonorycter froelichiella pupae, Mar.19th 2010. Reared from mines found in autumn 2009. Having survived one of the harshest winters on record they are removed from their mines and kept in an airtight jar with a tiny piece of damp tissue for humidity. Any condensation on the jar wall is removed daily to avoid mould forming on the pupae. Emergence is imminent as the wing pattern becomes visible.
358 Phyllonorycter froelichiella, Mar.20th 2010. Reared from the pupae illustrated above. Another variation of markings within this fascinating family of moths.
359 Phyllonorycter nicellii a tenanted mine in Common Alder at Bradshaw, Sept. 24th 2017.
363 Phyllonorycter joannisi = platanoidella mine in Norway Maple, Elland Bridge, July 2nd 2014. Also recorded from two areas of Manor Heath park.
363 Phyllonorycter joannisi = platanoidella, July 9th 2014. Reared from a mine found on "purple" Norway Maple at Manor Heath park in June.
363 Phyllonorycter joannisi = platanoidella, detail of the above moth. Being one of the smaller phyllos with a wingspen of 6-7 mm I had to use the Panasonic Lumix on full 24x zoom and still had to crop the photo a fair bit to get the desired image. Amazingly (to me at any rate) there is even some scale detail visible in this close-up view - I can't thank the people at panasonic enough for creating such a wonderful camera!
364 Phyllonorycter geniculella mine in Sycamore, towpath at Elland by-pass, July 2nd 2017. A common species, the mines are easy to find.
364 Phyllonorycter geniculella, June 20th 2014. Reared from a mine on Sycamore found in Bankhouse wood a few days previously.
366a Horse Chestnut Leaf Miner, mines on Horse Chestnut by the Calder at Hollas bridge, June 30th 2017. First discovered in Britain at Wimbledon in 2002 and in Calderdale in Oct. 2008 by Derek Parkinson. Since then it has rapidly spread throughout Calderdale with many trees now being severely affected.
366a Horse Chestnut Leaf Miner, May 25th 2014. An abundant species now, this one was found on my bedroom window.
368 Phyllocnistis unipunctella, one of two mines in poplar sp., Park Wood crematorium, July 28th 2010. A very distinctive "snail trail" mine. This is my only record.
