Nepticulidae
Mine under bark in small branches, giving vein like
appearance along branch [possible two year life cycle]
Ectoedemia
amani 41a
Frass
linear then variable; larvae green, exit hole underside of leaf
[8-9]
Stigmella
ulmivora 80
Frass
dispersed, sometimes coiled; larvae yellow, exit hole on top
of leaf [7+9-10]
Stigmella
lemniscella 63
N.B.
S. lemniscella can also make mines similar to S. viscerella.
To distinguish between
these
mines the initial S. viserella mine has a zigzag start whereas the mine of S.
lemniscella starts with concentric circles. Also the colour of the larvae is
different; S.
viscerella is green and S. lemniscella yellow.
Bucculatricidae
Mine
a slender gallery with linear frass leaving clear margins; there
are two to four frass free projections from gallery which end
abruptly. After leaving mine larva eats out windows from underside
of leaf [7-9]
Bucculatrix
albedinella 271
Mine
contorted at start filled with black frass, may double back on
itself forming a small blotch. Mine then straightens, often along
vein, finally turning away at an angle. After leaving mine larva
eats out windows from underside [5-7+8-10] …(In Britain,
at present it is found only in Surrey)
Bucculatrix
ulmifoliae 274a
Gracillariidae
Mine
underside of leaf, subcircular, strongly inflated. Larvae yellow,
gut green, pupae in a cocoon usually light green and cigar shaped
loosely attached to upper epidermis, often becomes loose when
mine opened [7+9-10]
Phyllonorycter
schreberella 352
Mine
underside tubular usually between two veins. Larvae pale whitish
green, pupae in an olive green cocoon, remains firmly attached
to lower epidermis when mine opened [7+9-10]
Phyllonorycter
tristrigella 356
Lyonetiidae
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]
