Classification
| Family: | Nepticulidae |
| Subfamily: | Nepticulinae |
| Genus: | Stigmella |
| Species: | svenssoni |
| Authority: | (Johansson, 1971) |
Local in woodland throughout much of the British Isles, although distribution poorly known owing to previous confusion with S. ruficapitella. First recorded in Hampshire in 1983 at Botley Wood, since when found to be sparsely distributed across much of south Hampshire, but remains very rare in north Hampshire and on the Isle of Wight. Wingspan 6-7 mm. Very similar to S. ruficapitella and S. roborella, from which separable only by dissection of the genitalia.
Larval mine on Quercus robur. The egg is usually laid on the underside of the leaf, the mine being a long, relatively wide gallery with linear black frass to begin with, subsequently neatly scattered, and finally more central and irregular, mostly occupying more than half the width of the gallery.
The abundance in each month is indicated as follows:
