Yorkshire Status: Very rare resident.

We have three records of this rare moth:

1. H.T. Stainton, writing in Ent. Weekly. Intell. 10:19 dated 15/4/1861 - "I happened to notice some blotched leaves of Stellaria holostea between here [Darnall] and Handsworth, and after making some closer search I observed that some of the blotches had the peculiar green tinge which is not infrequent in the mines of C. olivaceella but which I have never observed in the mines of C. solitariella. In a short time my suspicion was verified by the capture of a larva."
2. Thomas Wilkinson writing in Theakston's Guide to Scarborough in 1868 - "Larva common in Raincliffe Wood, feeds on Stellaria."
3. Thatchmire Farm, Eskavon, one to light on 6/8/2012. Dissected.

The usual food plant is greater stitchwort, though it can also apparently feed on sea campion, red campion, and mouse-ears. The confusion species is C. solitariella which as Stainton correctly pointed out in 1861, makes whitish blotches rather than the greenish-white blotches of lithargyrinella. The final case is tubular, 8mm long, with a dorsal keel which forks and continues as two ridges to the anal end of the case. The mouth angle is about 45°, and there are often several cases together on a small number of plants. This species could still occur in various parts of the county, hiding under the radar.

Verification Grade Comment: Case: Photo to show mouth angle & keel, otherwise = C4

	Determination by Genitalia Examination (gen. det.) Required

	Case: A good quality photo or specimen of the case and plant/pabulum is required.
