490 Coleophora lutipennella case on oak, North Dean wood, June 10th 2011. As with many Coleophora cases they are fascinating constructions made of silk and often incorporate sections of the foodplant to aid camouflage.
490 Coleophora lutipennella (female), reared from the larva above, June 28th 2011. Many thanks to Harry Beaumont for his time and knowledge in determining the identity of this moth in Jan.2012.
490 Coleophora lutipennella agg., case and larva at the base of an oak bud at Robber Dodge meadow, Stainland, Mar.31st 2016.
493 Coleophora serratella case and larva on Silver Birch, North Dean wood, May 6th 08. The larva can be seen mining the leaf whilst using the case as a safe retreat. One of the most easily found of all Coleophora cases in the spring.
493 Coleophora serratella, May 26th 08. Reared from the larva illustrated above.
495 Coleophora spinnella agg., first year case on Hawthorn, Copley meadow, May 26th 09. This case was formed in the autumn and used by the larva to overwinter in. In spring it makes a new, larger case to continue feeding.
495 Coleophora spinnella agg., case on Hawthorn, May 26th 09. This second year case was found next to the case illustrated above. To confirm the species the moth must reared through but unfortunately this one was parasitised. Note the mines and "puncture hole" to the right.
504 Coleophora lusciniaepennella case and larva on Goat Willow, the old sewage works at West Vale, Apr.28th 09. Again, the mine and puncture hole are visible.
504 Coleophora lusciniaepennella, feeding signs on Goat Willow. Details as above.

510 Coleophora juncicolella case, Mar. 23rd 2016. A beautifully camouflaged case constructed from mined Heather leaves. This one was inadvertently taken at Norland moor the previous day. It only came to my attention when I noticed the larva moving away from some Heather sprigs I had collected for my Northern Eggar larva.
At only 3mm in length the case was still under construction.
512 Coleophora binderella case and larva on Silver Birch, North Dean wood, May 12th 2011. This tiny case, just 4mm long was only noticed at home after inadvertently collecting it along with its foodplant to feed other larvae. The brown upper half of the case was built in the autumn and is what the larva overwinters in. The lower green half is the new addition in the spring and is still quite fresh and green.
518 Coleophora mayrella at Tag meadow, Cromwell Bottom, July 2nd 2017. A field observation among the Birdsfoot Trefoil. The sunlight has brought out the metallic colouring to the wings.
526 Larch Case-bearer larva and case on European Larch, Norland golf course, Apr.26th 2010. It appears to be common at this site.
541 Coleophora pyrrhulipennella case and larva, North Dean wood, May 6th 08. One of three swept from Heather by Paul Talbot.
541 Coleophora pyrrhulipennella, May 29th 08. Reared from the larva above. Quite a showy species by Coleophora standards!
563. Coleophora argentula, case and larva on a Yarrow seedhead, Hollas Lane nature reserve, Sept. 2nd 2017.
563. Coleophora argentula case, details as above. After taking the case home for further study I was surprised to find it was tenanted. At the time of writing the larva was feeding away on the Yarrow seeds.
582 Coleophora glaucicolella and 584 Coleophora alticolella cases on juncus, Milner Royd drain, Feb.13th 09. Larvae were identified from a sample of cases collected from here and C.alticolella was much the more common species present with just one larva of C.glaucicolella found. Also some cases were empty or parasitised.
584 Coleophora alticolella, case on a rush species at Copley meadow on Feb.24th 2016. The cases were still quite easy to find despite the host plants being on the flood plain that was severely affected by the devastating Boxing Day floods a couple of months earlier
584 Coleophora alticolella, larva extracted from the case pictured above. It nicely shows the sceleratised patches on the thoracic segments.
584 Coleophora alticolella, June 18th 09. Reared from cases found at Milner Royd drain (gen.det. Charlie Streets).
