ERIOCRANIIDAE.


6 Eriocrania subpurpurella , larva and mine in oak, Bankhouse wood, May 11th 09. A widespread and abundant species almost anywhere there are oaks.

6 Eriocrania subpurpurella, Apr.14th 2014. Captured by day at New Lane. After nine years with my old Coolpix 4500 I decided it was time for an upgrade so I purchased the Panasonic Lumix FZ200 with the DCR 250 clip-on Raynox lense. It's early days but this shot shows both the fine detail that can be captured and also the very shallow depth of field at the higher end of the zoom - the eye's in focus but not the nose!

8 Eriocrania unimaculellalarva and mine in Silver Birch, North Dean wood, May 17th 2010. Note the two distinctive dark brown spots on the rear of the head capsule. I've found this to be a common leaf miner at this site.

8 Eriocrania unimaculella, Feb.28th 2011. A freshly emerged moth still drying its wings, hence the uncharacteristic posture. Reared from mines found on Silver Birch the previous May in North Dean wood. 


8 Eriocrania unimaculella Mar.1st 2011. Reared from mines as above. A beautiful little moth not much more than 5mm long and one of my most satisfying photos.


9 Eriocrania sparrmannella mine and mature larva in Silver Birch, North Dean wood, June 12th 2011. Note the initial corridor (to the lower right) is overtaken by the blotch, but remains recognisable in the frass pattern. A much later miner than the more commonly recorded Eriocrania species. This is my only record.


10 Eriocrania salopiella, mine in Silver Birch from North Dean wood. An illustration as to how quickly these mines are formed. As with E.sparrmannella, the mine usually starts near the midrib.


11 Eriocrania cicatricella, mine and larvae in Silver Birch, North Dean wood, May 9th 09. Larvae pale with often more than one to a mine. The mine itself is not completely eaten out giving rise to greenish blotches. A fairly common species at this site.


11 Eriocrania cicatricella, Feb.27th 09. Reared from mines on Silver Birch found in North Dean wood the previous May.

12 Eriocrania sangii, mine and larva in Silver Birch, North Dean wood, May 4th 09.


12 Eriocrania sangii, larva in Silver Birch, North Dean wood, May 4th 09. The opened mine reveals the diagnostic grey larva as well as the "spaghetti" frass typical of Eriocrania species.



13 Eriocrania semipurpurella, larva and mine in Silver Birch, North Dean wood, May 5th 09. This mid-instar larva will lose the dark sclerotised skin on the head capsule on reaching maturity.

13 Eriocrania semipurpurella, Feb.27th 2011. A newly emerged adult.


13 Eriocrania semipurpurella, Mar.2nd 2011. Reared from mines found last spring in North Dean woods. The larvae vacated the mines into plant pots containing potting compost and were left outside until the following spring, by which time the pupae contained fully formed adults. The pots were then brought indoors in late February when the adults began to emerge after just 5 days.


13 Eriocrania semipurpurella, Mar.5th 09. One of the commonest and widespread of the birch feeding Eriocrania occasionally seen resting on their foodplant on cool, spring days.

Hi Ron,

The mines on birch are generally easy to find and often produce several species - the adults though are more elusive.

Good luck.
