2013 (CHF): Since its discovery in the county in 1996, this species has proved to be one of the most commonly encountered species of oak-feeding Stigmella, both as adults to light and leaf mines. Along with most of the other oak-feeding Stigmella species it cannot be safely identified as a mine and the adult should be bred out. The egg is laid on the underside of the leaf, almost always close to a thick vein. The mine is a fairly long, rather slender corridor. The frass is in a broad, often interrupted central band and may be coiled. The mine is quite variable. This species also mines sweet chestnut and is (probably!) the only Stigmella to do so in Britain.
