Leaf-miner: A narrow gallery, tending to follow veins of leaf. The early part
with linear frass (British
leafminers).
Oviposition
at the underside of the leaf, mostly close to a vein. The mine is
a long, very slender corridor; even towards the end hardly wider
than necessary to accomodate the growing larva. Frass in a narrow
central line. The shape of the mine differs somewhat between the
hostplants. In Carpinus the mine closely follows a heavy
vein over a long distance; also the mine tends to be somewhat shorter
and broader, and the frass often lies in a more diffuse line. The
mines in Corylus are not so strictly defined by the venation
and the frass line is narrower (Emmet, 1983a; Johansson et al.,
1990a). Sometimes it is difficult to separate the mines from those
of S. floslactella ;
an additional difference then is that even in the very first part
of the corridor the frass of microtheriella lies in a narrow
line, while the frass of floslactella seems to fill the entire
corridor there. The pale golden larva lies venter-upwards in the
mine (Bladmineerders van Europa).
Sometimes
there can be several larvae mining the same leaf (UKMoths).
The mine is illustrated in the Encyclopedia of Life.
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
The larva is yellow, head pale brown (British
leafminers).
The
larva is illustrated in Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Adult:
The adult is illustrated in UKMoths.
The species is included in mothdissection.co.uk.
