282 Caloptilia elongella feeding signs on alder, Milner Royd drain, Sept.16th 09. First the larva creates an upperside, elongated, silvery blotch, then it leaves the mine and rolls the leaf edge downwards to feed in. This is my only record.
284 Caloptilia rufipennella, a rolled leaf tip and two blotch mines on Sycamore, Bankhouse wood, June 19th 2014.
284 Caloptilia rufipennella, a 6mm long blotch mine in Sycamore, Bankhouse wood, June 12th 2014.
284 Caloptilia rufipennella, July 7th 2014. Reared from the larva in the rolled leaf edge pictured above.
286 Caloptilia alchimiella mines and feeding signs on oak, Crimsworth Dean, Hardcastle Crags, Aug.18th 2012. This is my only record. There are two vacated mines made by separate larvae, one of which has gone on to make the neat, cone shaped fold at the leaf tip in which to feed.
286 Caloptilia alchimiella, a folded leaf edge, Aug.22nd 2012, details as above. A few minutes after introducing the larva to a fresh leaf it rapidly began to spin the leaf edge over. Countless threads of silk are spun which, as they begin to dry, contract so by pulling the leaf edge over.
286 Caloptilia alchimiella, cocoon under a spun leaf edge. After nearly four weeks the larva has finally spun up to pupate. The subsequent pupa was identified by Willem Ellis as being of this species and not the very similar Caloptilia robustella.
286 Caloptilia alchimiella pupa, Apr.27th 2013. After spending the winter in the garage in an airtight tuppaware box the pupa was brought indoors on Apr.4th. After just over three weeks it has begun to colour up nicely shortly before emergence.
286 Caloptilia alchimiella, Apr.30th 2013. Freshly emerged from the pupa illustrated above.
288 Caloptilia stigmatella, a rolled leaf tip on Goat Willow, the towpath near Elland Bridge, Sept.13th 09. This is my only record.
293 Caloptilia syringella mine on garden Privet, Skircoat Green, June 6th 2014.
293 Caloptilia syringella, a tightly rolled leaf on garden Privet, June 6th 2014. Several days later when opened up to change the occupants to a fresh leaf there were no less than four larvae present.
293 Caloptilia syringella, June 28th 2014. Reared from the larvae in the leaf fold pictured above.
293 Caloptilia syringella, a mating pair, North Dean wood, May 16th 05. A field observation.
294 Aspilapterix tringipennella, mine (centre) on Ribwort Plantain, Tag meadow, Apr.21st 2014. The internal spinning eventually causes the leaf to pucker and fold. Mines seem to be a lot more readily found here than in many other areas nearby.
294 Aspilapterix tringipennella, (Above and below) May 5th 2014. Both reared from larvae found in mines on Ribwort Plantain at Tag Loop (see above).
301 Parornix betulae, feeding signs on Silver Birch, Elland Bridge, Sept.16th 2010. At first a brown phyllonorycter type mine is formed and then the larva feeds in a folded leaf edge. This is my only record.
303 Parornix anglicella, mine on Hawthorn by the Calder at Milner Royd, June 30th 2017.
304 Parornix devoniella, feeding signs on Hazel, New Lane, July 10th 09. An agular blotch mine centre and then on to a small folded leaf edge top right. This is my only record.
305 Parornix scoticella larva and feeding signs on Rowan, North Dean wood, Sept.20th 2010. This is my only record.
308 Parornix finitimella mine and folded leaf edge on Blackthorn, Park Wood crematorium, July 18th 2017.
310 Callisto denticulella mine on Apple, Skircoat Green allotments, July 9th 2017. An initial gallery opening out to an orange blotch.
