– Leaf-miner
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: S.microtheriella and M. tityrella
ID pointers: An overall light brown or greyish upper-wing covered in coarse yellowish or silvery scales. A light orange-pale yellow head and a pale cross-band at about a third, bordering the darker final third of the wing. Whitish cilia.
Distribution: (Last record: 24 November 2025 at Glossop, Long Clough ) – With few records of any adults and most relate to the Leaf mines, the species is obviously present in the county in wide scattered localities but relatively uncommon.
General Comment: Notes by Christian Heintzen on Stigmella floslactella – On Hazel – 24th Nov 2025 – Long Clough, Glossop – on Hazel (Corylus) (A) > long corridor/gallery intially filled with green frass (B,C) > final larval chamber broader than larva (B) > exit slit on upper surface of leaf (D) > egg in or at vein [E] ©
Mine Period Additional: more frequently found in Sept-Oct
Mine ID Difficulty:
– Care required in ID process as confusion with similar leaf mines. Quality photos of the mine required. Mine Type/s: Gallery
Mine Feeding Method/s: Not Recorded
Mine Comment: The larva creates a long slender, gradually widening corridor mine in the leaf. The frass in the mine is initially a green line but later becomes scattered in irregular arcs and clouds. The best means of identification is the position of the egg within the mine. The egg is always laid in a vein axil on the underside of a leaf, this helps to identify it from S.microtheriella which most often lays its egg in a vein but not in the axil (A leaf axil is the angle or space fromed where a smaller vein branches off from a larger vein on a leaf). The mines are often found alongside S.microtheriella on the same leaf.
