LISTERA. Twayblades. [Orchidaceae]

Two species of Listera, Common Twayblade (L. ovata) and Lesser Twayblade (L. ovata), are recorded in Britain. Both are native. Listera ovata is treated as Neottia ovata by Stace (2010).

Only one British miner is recorded on Listera.

A key to the European miners recorded on Neottia including Listera is provided in Bladmineerders van Europa.

Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Listera

1 > Leaf-miner: Large blotch with a group of some larvae. At the start of the mine a group of elliptic egg shells.

The larvae make individual mines which then merge to form an upper surface blotch. The larva leaves the mine to pupate.

On Listera in Britain, but not common. On Cephalanthera, Cypripedium, Dactylorhiza, Epipactis, Gymnadenia, Ophrys and Orchis elsewhere. Widespread in Britain and continental Europe. Also recorded in the Republic of Ireland and from the Nearctic region

Parallelomma vittatum (Hering, 1826) [Diptera: Scathophagidae].
