15.025 Brown Birch Slender (Parornix betulae), feeding signs on birch at Maple Dean clough, North Dean wood on June 17th 2020. At first a brown Phyllonorycter type mine is formed and then the larva feeds in a folded leaf edge.
15.028 Hawthorn Slender (Parornix anglicella), mine and folded leaf edge on Hawthorn by the towpath at Elland Bridge, Aug. 10th 2017. A very common species whose feeding signs are easily found.
15.029 Hazel Slender (Parornix devoniella), mine and folded leaf edge on Hazel at Hollas Lane, Copley, Aug. 13th 2017. An angular blotch mine against the mid-rib, lower left and then on to a small, folded leaf edge at the top. Quite easy to find once familiar with these two signs.
15.029 Hazel Slender (Parornix devoniella), mine and feeding larva on Hazel, Aug. 19th 2019. Found at Shibden Dale two days earlier.
15.029 Hazel Slender (Parornix devoniella), exposed larva, Aug. 22nd, from the mine pictured above.
15.030 Rowan Slender (Parornix scoticella) larva and feeding signs on Rowan, North Dean wood, Sept. 20th 2010.
15.032 Pointed Slender (Parornix finitimella) mine and folded leaf edge on Blackthorn, Park Wood crematorium, July 18th 2017.

15.033 Blackthorn Slender (Parornix torquillella), final instar larva inside the folded leaf pictured above. Its legs are concolourous with its body which rules out P. finitimella.

15.033 Blackthorn Slender (Parornix torquillella). Three days later and the above larva had spun a yellowish cocoon to pupate in - which it did successfully.
15.034 White Oak Midget (Phyllonorycter harrisella) pupa found on oak at Norland village on Feb. 2nd 2012. As the moth forms inside the pupa the eyes begin to darken and the wing pattern slowly develops. Moments before emerging the exarate nature of the pupa becomes apparent, this is where the appendages are free from the main body of the pupa.
After wriggling and writhing for some minutes the moth broke through the pupal case and emerged in a matter of seconds. It was quite some performance extracting all its delicate limbs and antennae from the casing. This photo shows the wings around half way free.
Half way out and already you can see there is hardly a scale out of place. As I've already got a satisfactory photo of this species (to me at any rate) this one was left in peace to fly off to its well earned freedom.
15.034 White Oak Midget (Phyllonorycter harrisella) New Lane, May 3rd 2010. One of two flying in the early morning sun - captured by hand!
15.035 Gold-bent Midget (Phyllonorycter roboris), Bankhouse wood, May 5th. Disturbed and captured by day.
15.035 Gold-bent Midget (Phyllonorycter roboris), a mating pair on oak, North Dean wood, June 1st 2010. Captured by day.
15.039 Common Oak Midget (Phyllonorycter quercifoliella) mine and cocoon in oak, North Dean top, July 2nd 09. The larva spins its cocoon with a covering of its own frass in the summer generation - visible as the dark oval in the mine. It maybe a good deterrent for birds but is less effective against the long ovipositors of parasitic wasps.
15.039 Common Oak Midget (Phyllonorycter quercifoliella) mine (left) along with a Stigmella mine in oak, Eaves Top wood, Stainland, Nov. 23rd 2016.
15.039 Common Oak Midget (Phyllonorycter quercifoliella) pupa in oak, Tag meadow, Dec. 14th 2013. In the autumn generation the pupa is surrounded by "U"shaped frass.
15.039 Common Oak Midget (Phyllonorycter quercifoliella) on oak, Long wood, Apr. 26th 2014. There were good numbers of these resting on oak trunks in the mid-afternoon sun. It's very refreshing to be able to photograph these moths in their natural setting for a change as oppose to trying to get reared moths to stay still on a staged substrate.
