GRACILLARIIDAE: 67 - END

15.067 Common Alder Midget (Phyllonorycter rajella) mines in Common Alder at Tag meadow, Cromwell Bottom, Nov. 28th 2016.

15.067 Common Alder Midget (Phyllonorycter rajella) mine and empty pupal case in Common Alder by the towpath at Sowerby Bridge, Sept. 6th 08. The mine usually has a single crease on the underside.

15.067 Common Alder Midget (Phyllonorycter rajella), July 5th 2014. Reared from mines found by the towpath at Sowerby Bridge on June 25th 2014.

15.073 Fiery Oak Midget (Phyllonorycter lautella) mine in oak at Norland village, July 14th 2017. Typically longer than the more common oak Phyllo mines, this one is 20mm long. 

15.073 Fiery Oak Midget (Phyllonorycter lautella) Apr. 12th 2011. Reared from a mine at Norland village found 12 days earlier. As many of the leaves persist on oak trees throughout the winter it is quite easy to find the autumn generation pupae of oak feeding Phyllos well in to the spring.

15.073 Fiery Oak Midget (Phyllonorycter lautella) July 12th 2018. Reared from a mine found at Tag meadow 6 days earlier.

15.075 Red Birch Midget (Phyllonorycter ulmifoliella) mine in birch near the cafe at Cromwell Bottom, June 25th 2017.

15.075 Red Birch Midget (Phyllonorycter ulmifoliella) July 7th 2019. Reared from a mine in birch from the woods by Cromwell Bottom cafe a couple of weeks earlier.

15.076 Large Midget (Phyllonorycter emberizaepenella), a tenanted mine on Snowberry near Cromwell Bottom cafe on Oct. 16th 2018.

15.076 Large Midget (Phyllonorycter emberizaepenella) mines collected from the shrub pictured above. They are generally large mines which cause the leaf to fold longitudinally rather than transversely. I find it best to wait until pupation to clinch a positive ID (see below).

15.076 Large Midget (Phyllonorycter emberizaepenella) cocoon. A day after the mines were collected one of the larvae had spun this olive-green cocoon which will turn brown in due course. The closely related Honeysuckle Midget larva doesn't spin a noticeable cocoon.

15.076 Large Midget (Phyllonorycter emberizaepenella) Feb. 17th 2019. After spending the winter in my garage in a tuppaware box the pupae were brought indoors and about a month later the first adult has emerged.

15.076 Large Midget (Phyllonorycter emberizaepenella) mine and folded leaf on the garden Honeysuckle, Sept. 15th 2018.

15.076 Large Midget (Phyllonorycter emberizaepenella) larva from a mine in the plant pictured above, Sept. 24th 2018.

15.078 Elm Midget (Phyllonorycter tristrigella), mine in Wych Elm by the towpath above Cromwell Bottom, Nov. 28th 2016.

15.078 Elm Midget (Phyllonorycter tristrigella), empty pupal case and cocoon reared from mines in Wych Elm found at Bankhouse wood the previous autumn. Having retrieved the cocoon from the decomposed mines I left outside over winter I wasn't sure what, if anything was still alive inside - so I was pleasantly surprised when the moth below emerged in perfect condition.

15.078 Elm Midget (Phyllonorycter tristrigella), Mar. 17th 2010. This moth emerged from the pupal case pictured above.

15.079 Small Alder Midget (Phyllonorycter stettinensis) in Common Alder at Cromwell Bottom, Sept. 14th 2019. Not much to look at this one, the leaf seems more contorted than usual but you can still see that it's an upperside mine with a central crease.

15.079 Small Alder Midget (Phyllonorycter stettinensis), underside of the mine pictured above.

15.080 Broad-barred Midget (Phyllonorycter froelichiella) pupae Mar. 19th 2010. They were reared from mines collected in Common Alder by the towpath at Brighouse the previous autumn. The wing pattern has developed nicely a day before the moths start to emerge (see below).

15.080 Broad-barred Midget (Phyllonorycter froelichiella) mines and larvae in Common Alder by the Calder at Copley village, Oct. 1st 2017.

15.080 Broad-barred Midget (Phyllonorycter froelichiella), Mar. 20th 2010. Reared from the pupae pictured above.

15.080 Broad-barred Midget (Phyllonorycter froelichiella) mine in Grey Alder at Moorside, Cragg Vale on Oct. 6th 2021. The larva was identified.

15.081 Red Hazel Midget (Phyllonorycter nicellii) mine in Hazel at Birdcage Hill, Copley on July 1st 2020.

15.084 Maple Midget (Phyllonorycter acerifoliella) mine in Field Maple at New Lane on Sept.15th 2017.

15.085 White-bodied Midget (Phyllonorycter joannisi) mine in Norway Maple at Elland Bridge, July 2nd 2014.

15.085 White-bodied Midget (Phyllonorycter joannisi) cocoon and pupa. An opened mine in "purple" Norway Maple from Manor Heath Park, July 2nd 2014.

15.085 White-bodied Midget (Phyllonorycter joannisi) reared from the pupa pictured above. Even with my Panasonic Lumix on full 24x zoom the original image still needed cropping a fair bit to get the moth to a reasonable size.

15.086 Sycamore Midget (Phyllonorycter geniculella) mine in Sycamore by the towpath near Elland By-pass, July 2nd 2017.

15.086 Sycamore Midget (Phyllonorycter geniculella), June 20th 2014. Reared from a mine in Sycamore found at Bankhouse wood 10 days earlier.

15.089 Horse-chestnut Leaf-miner (Cameraria ohridella) - countless mines in Horse Chestnut at Hollas Bridge, Copley, June 30th 2017. A fantastically healthy population - although some would call it an infestation!

First discovered in Britain in Wimbledon in 2002 and in Calderdale in Oct. 2008 by Derek Parkinson. Since then it has spread rapidly throughout Calderdale with almost all trees now being severely affected.

15.089 Horse-chestnut Leaf-miner (Cameraria ohridella) mines in Sycamore at Luddenden Foot on Aug. 4th 2022.

The tree is situated underneath a Horse Chestnut heavily populated with Horse-chestnut Leaf-miners.

 

15.089 Horse-chestnut Leaf-miner (Cameraria ohridella) mines in Sycamore at Luddenden Foot on July 12th 2022. I hadn't realised these mines could be found on anything else other than Horse Chestnut.

15.089 Horse-chestnut Leaf-miner (Cameraria ohridella), May 25th 2014. This obliging individual was found crawling up the outside of my bedroom window.

15.092 Poplar Bent-wing (Phyllocnistis unipunctella), one of two mines in a poplar sp. at Park Wood crematorium, July 28th 2010. A very distinctive "snail trail" mine.
