Leaf miner:
A flat blotch at the leaf margin. The leaf is not rolled inwards over the mine. Rarely more than one mine per leaf. Mines mainly in the canopy. Frass grains elliptic, abbout 0.5 mm long (Bladmineerders van Europa).

The 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 a pale brown, with pale brown head (British leafminers).

Pupa: The pupae of sawflies have visible head appendages, wings and legs which lie in sheaths.

Adult: Details unkinown.

Distribution in Great Britain and Ireland: Discovered in the UK in June 2007 by Keith Palmer. More mines were then confirmed in Cheshire by Steve Hind. By 2009 it was found to have a wide distribution in the UK. East Norfolk, South Lancester and Surrey (NBN Atlas).

Distribution elsewhere: Currently unknown. No map.

NBN Atlas links to known host species:
