37.005 Common Oak Case-bearer (Coleophora lutipennella), a tenanted case on oak, North Dean wood, June 10th 2011. As with many Coleophora cases they are fascinating constructions made of silk and they often incorporate sections of the food plant to aid camouflage.
37.005 Common Oak Case-bearer (Coleophora lutipennella) - female, reared from the larva above, June 28th 2011. Thanks to Harry Beaumont for his time and knowledge in determining the identity of this moth in Jan. 2012.
37.006 Rose Case-bearer (Coleophora gryphipennella) mines and case on Dog Rose at Pickwood Scar, Sept. 27th 2017. Possibly old mines and a case from the spring.
37.015 Common Case-bearer (Coleophora serratella) case and larva on birch, Exley Bank wood, Apr. 30th 2018. The larva can be seen mining the leaf as a dark blob in the upper mine. A second mine below shows the trademark, circular puncture hole.

37.015 Common Case-bearer (Coleophora serratella), May 26th 08. Reared from a larva found in North Dean wood earlier in the month.
37.016 Apple & Plum Case-bearer (Coleophora spinella) 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 larger case to continue to feed from.
37.016 Apple & Plum Case-bearer (Coleophora spinella) larva, case and mines on Hawthorn at the cycle-way at Luddenden Foot on May 9th 2022.
Apple & Plum Case-bearer (Coleophora spinella) female, reared from the case pictured above on June 23rd 2022. Gen. det. (CS).

37.028 Least Case-bearer (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.
37.030 Grey Alder Case-bearer (Coleophora binderella) case and larva on birch, North Dean wood, May 12th 2011. This tiny case, just 4mm long was only noticed at home after accidentally 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 overwintered in. The lower half is the new addition in the spring and is still quite fresh and green.
37.034 White-clover Case-bearer (Coleophora frischella) in cop at Clock Face quarry on May 29th 2022. They were swept from Red Clover by Anthony Arak who has found them to be quite easy to find both here and at a site in Barkisland by using this method. These and 10 others of both sexes were gen. detted. (CS).
37.046 Red-clover Case-bearer (Coleophora deauratella ), a female, at Tag meadow, Cromwell Bottom, July 2nd 2017. A field observation among Birdsfoot Trefoil. The sunlight has brought out the metallic colouring on the wings.
Meadow Case-bearer (Coleophora mayrella) at Brearley meadows below Midgley on June 2nd 2022. Swept from vegetation consisting mainly of grasses and buttercups with small amounts of Red Clover in among. It has distinctive ringed antennae with the basal two fifths scaled.

37.055 Ling Case-bearer (Coleophora pyrrhulipennella), May 29th 08. Reared from the larva above. Quite a showy species by Coleophora standards!
37.044 Lotus Case-bearer (Coleophora discordella) mines on Birds-foot Trefoil, Cromwell Bottom, May 12th 2018. Both mines and puncture holes are easily visible on the upper surface.
37.044 Lotus Case-bearer (Coleophora discordella), a tenanted case and mine, details as above. While the larva was constructing the case out of excised leaf fragments it even included a piece of old mine.
37.102 Yarrow Case-bearer (Coleophora argentula) case and larva on a Yarrow seedhead, Hollas Lane nature reserve, Sept. 2nd 2017. After taking the case home for further study I was surprised to find it was tenanted and actively feeding on the Yarrow seeds.
37.102 Yarrow Case-bearer (Coleophora argentula) cases on Yarrow seedheads, Sept. 19th 2018. Illustrating the abundance of this species here, there are around 17 cases on this one plant.
37.102 Yarrow Case-bearer (Coleophora argentula), two tenanted cases on a Sneezewort seedhead, Hollas Lane nature reserve, Oct. 8th 2019. The cases are easy to find here.
37.071 Grey Rush Case-bearer (Coleophora glaucicolella) and Coleophora alticolella cases on juncus, Milner Royd drain, Feb. 13th 09. Larvae were identified from a sample of 11 cases collected from this site and C.alticolella was much the more common species present with just one larva of C.glaucicolella. Also some cases were empty or parasitised.
Grey Rush Case-bearer (Coleophora glaucicolella) to MV light at Mirey Wall farm near Sowerby on June 24th 2022. Gen. det. (CS).
37.073 Common Rush Case-bearer (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
37.073 Common Rush Case-bearer (Coleophora alticolella) larva extracted from the case pictured above showing the sceleratised patches on the thoracic segments.
37.073 Common Rush Case-bearer (Coleophora alticolella), June 18th 09. Reared from cases found at Milner Royd drain. Gen. det. (CS).
Dark Thistle case-bearer (Coleophora paripennella) on knapweed at Scarborough on Apr. 25th 2022. Two cases and numerous mines with trademark puncture holes. I've searched many times at various sites for this species in Calderdale without success. Whilst on holiday I casually glanced at the first knapweed plant I saw and found these. It was found elsewhere that week which goes some way towards supporting my theory that Calderdale is an explicable, lepidopterous black hole when it comes to finding some species which are common elsewhere in Yorkshire.
