Leaf-miner
and case-bearer:
The larva forms a distinctive black case from silk, from which it
feeds on the foliage or flowers of heather or bell heather. The
larval case reaches around 9 mm in length when fully fed (UKMoths).
The
shiny black case is also illustrated in British
leafminers and described in (Bladmineerders van Europa).
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).
See Emmet et al. (1996a), Suire (1961a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The pupa is formed in the larval case, which is attached to
the tip of a shoot in full sunshine (UKMoths).
Adult:
The adult is illustrated in UKMoths by Tymo Muus.
The species is included in mothdissection.co.uk.
