Leaf-miner: A contorted gallery leading to blotch. Larva greenish-white with
dark ventral spots (British
at the underside of the leaf, usually not far from the midrib. The
mine is a corridor; its first part is strongly contorted, intestine-like,
containing brown, coiled, frass. The last part may follow the leaf
margin for some distance. In the end the corridor widens into an
elongate blotch with dispersed frass. The larva mines venter upwards.
Pupation external (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).
The young larva has a chain of dark spots on the abdomen, which
can be seen from above the mine, since the larva mines venter upwards.
In later instars, these spots become smaller and less noticeable,
and the green gut can be seen (UKMoths).
The larva is illustrated in British
leafminers and Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths.
genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
Sanguisorba minor is
treated as Poterium sanguisorba (Salad Burnet) by Stace (2010).
