Description

The wingspan is 6–7 mm. The thick erect hairs on the head vertex are ochreous-yellowish to fuscous. The collar is pale grey. Antennal eyecaps are whitish. The front wings are bronze-fuscous with a broad somewhat shining whitish fascia beyond middle; apical area beyond this is rather dark purplish-fuscous. Hindwings are light grey.[2] Adults are on wing in May.[3]

Leaf mine
Ovum

Laid on the underside of a leaflet, often close to the midrib.[4]

Larva

The larvae feed on Amelanchier, Himalyan cotoneaster (Cotoneaster simonsii), apple (Malus domestica), rowan (Sorbus aucuparia) and Swedish whitebeam (Sorbus intermedia), mining the leaves of their host plant. The mine starts as a slender winding corridor, the second part of which is almost filled with frass. The corridor then widens into a blotch with dispersed frass. In large leaves this blotch may be almost circular. Normally, the midrib is not crossed, but the mine can occupy the major part of a leaflet. There are often several mines in a leaf.[4][5]

Pupa

In a brown cocoon spun on detritus.[4][6]

Distribution

Found in Asia and most of Europe (except Iceland, Portugal, Belgium, and the western part of the Balkan Peninsula)

Etymology

Stigmella sorbi was described by the English entomologist, Henry Tibbats Stainton in 1861 from a type specimen found in Scarborough, Yorkshire. The genus Stigmella – ″stigma″, refers to the conspicuous (or occasionally metallic) small dot or a brand fascia on the forewing of many of the Stigmella species, or possibly the small size of the moths. The species name sorbi – refers to rowan Sorbus aucuparia', one of the larval foodplants.[7]
