Upper-surface tentiform mine (according to Hering, 1957a, mostly
lower-surface in Laburnum). The mine is strongly contracted, almost
folding the leaflet to a pod and concealing the mine. Pupa in the
mine in a flimsy cocoon. Frass in a corner of the mine (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).
Head pale brown, body deep yellow (Emmet et al., 1985) - a very
unusual colour for a gracillariid larva (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
