quickly and strongly widening from the start. Frass in sausage-shaped

mine is also illustrated in British
leafminers.
Larva:
The larvae of sawflies have a head capsule, chewing mouthparts with opposable mandibles, six thoracic legs and abdominal legs (although they may be reduced) (see examples).
The larva is illustrated in Bladmineerders van Europa and British
leafminers.
