Mine
a long sinuous gallery, often whitish in appearance and often
crossing midrib. The egg is laid inside the leaf being injected
through the epidermal layer. This feature helps to distinguish
it from a Nepticulid mine where the egg is laid on the surface
of the leaf [5+7+9-10]

Stigmella
perpygmaeella.
Usually
on top beside the midrib. Difficult to find.
Gallery
slender; broken linear frass following rib or leaf margin
usually reverses direction; may go down petiole. Makes a
false blotch, compact frass near the beginning of blotch,
may be coiled [7+10]
Pale
yellow, head brown

Stigmella
oxyacanthella
Underside, usually close to a rib.
Long
slender gallery following rib or leaf margin with linear
frass sometimes going down petiole. Mine becomes broad filled
with coiled reddish frass. Mine long, not forming blotch,
but often making hairpin bends [9-10]
Bright
green, head pale brown to dark grey.
108
Stigmella
crataegella
Underside,
usually near midrib at base of leaf.
Mine
starts slender with linear frass, usually following rib or
leaf margin or along petiole. Gallery broadens abruptly with
now coiled frass filling the gallery, before finishing with
a central line. Gallery doubles back on itself forming a
false blotch [6-8]
Bright
green, head green.

Stigmella hybnerella
Almost
always underside beside a vein away from the margin.
Starts
as a slender more or less direct gallery, with black linear
frass and narrow clear margins. Larva now changes to blotch
feeding, usually near leaf margin [5-6+8-9]
Whitish
with faint yellow tinge, head brown
107
Stigmella
regiella
Underside
near margin
Narrow gallery with reddish frass following leaf margin often
doubles back on itself making a parallel mine before expanding
abruptly into a blotch with blackish frass deposited irregularly
in the centre. Blotch often absorbing earlier workings. [8-11]
Yellow,
head pale brown. Cephalic ganglia conspicuous.
29
Ectoedemia
atricollis
Underside
Starts
as an erratic gallery zigzagging to and fro in a small area
near the egg. The mine then usually follows the leaf margin,
filled with frass which leads to a blotch with the frass
scattered [8-10]
Whitish, head dark brown. Gut dark green or reddish
