Morley’s Final Catalogue: Common on stitchwort; bred at Waldringfield in 1934 (Trans, ii, clxviii); Nayland-Stoke, Ipswich and Framsden, bred (Whit).

Recent Status: A rarely recorded species in Suffolk.

Life Style: The moth is single brooded flying during July. The larvae mine leaves of Stellaria holostea. They hibernate when young and resume feeding in the year following oviposition before pupation in the larval case.

Identification: This species is very similar to C. lithargyrinella both in the appearance of the adult and the larval case and feeding. The adult moths also have similarities to C. flavipennella and C. lutipennella. The moths are light ochre to orange ochre paler towards the base of the costa. The dorsal cilia of C. lithargyrinella are ochreous buff, in C. solitariella they are grey.
The larvae produce blotch mines. The first is excised to become the portable case. They extend the case with silk. They eventually have a trivalved anal opening but in C. solitariella this is bivalve until the final instar. They have a dorsal and ventral ridge but in the final instar of C. lithargyrinella the dorsal ridge becomes bifid at around half length. The blotch mines of C. lithargyrinella are greenish white and white for C. solitariella. More Info
