[Tenthredinidae]


Scolioneura vicina Konow, 1894

Leaf miner: Large, transparent, in fresh condition pale green blotch that begins at the leaf margin, without an accumulation of frass. Mine and larva are undistinguishable from those of S. betuleti (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 pale green, with a brown head (British leafminers). The larva is also illustrated in Bladmineerders van Europa.

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

Adult: The adult is illustrated in ECatSym - Electronic World Catalog of Symphyta.

Hosts in Great Britain & Ireland:

Betulaceae

Betula pendula Silver Birch British Wild Flowers by John Somerville et al. British leafminers
Betula verrucosa White Birch   British leafminers

Hosts elsewhere:

Betulaceae        
Betula papyrifera Paper birch   Bladmineerders van Europa
Betula pendula Silver Birch British Wild Flowers by John Somerville et al. Bladmineerders van Europa
Betula pubescens Downy Birch British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - larvae: May - June (British leafminers).

Time of year - adults: Currently unknown.

Comments: Full synonymy and references are listed in ECatSym - Electronic World Catalog of Symphyta.

Distribution in Great Britain & Ireland: A female was found in May 1942 in Ireland (Liston and O'Connor, 2005) and the species has subsequently been recorded in mainland Britain (British leafminers - Newsletter 12).

Distribution elsewhere: Widespread in continental Europe including Austria, Belgium, Finland, Germany, Luxembourg and Sweden (van Achterberg in Fauna Europaea).
