37: COLEOPHORIDAE.

37.005 Common Oak Case-bearer (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 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 case from last spring.


37.015 Common Case-bearer (Coleophora serratella) case and larva on birch, Siddal 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) 1st year "pistol" case found in close proximity to the case pictured above. 




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 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 larger case to continue feeding from. 


37.016 Apple & Plum Case-bearer (Coleophora spinnella) agg., case on Hawthorn, May 26th 09. This second year case was found next to the case pictured 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.


37.022 Osier Case-bearer (Coleophora lusciniaepennella), a tenanted case on Goat Willow at Copley village, May 15th 2018.

37.022 Osier Case-bearer (Coleophora lusciniaepennella)newly emerged adult and case, May 24th 09. One of two reared from cases found at West Vale - details as above.

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 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. 


37.048 Meadow Case-bearer (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.


37.066 Larch Case-bearer (Coleophora laricella), a tenanted case and mine on European Larch, Rishworth golf course, Norland, May 10th 2018.


37.066 Larch Case-bearer (Coleophora laricella) larva and case, details as above. It appears to be quite common at this site.


37.055 Ling Case-bearer (Coleophora pyrrhulipennella) case and larva, North Dean wood, May 6th 08. One of three swept from Heather by Paul Talbot.

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. Whilst constructing the case out of excised leaf fragments it's 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.

37.102 Yarrow Case-bearer (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.


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 found. Also some cases were empty or parasitised.

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. It nicely shows 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. Charlie Streets).
