The leaf and stem mines of British flies and other insects

(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

by Brian Pitkin, Willem Ellis, Colin Plant and Rob Edmunds


BEGONIA. Begonia. [Begoniaceae]

Three Begonia species are recorded in Britain. All are introduced.

Only one Britisdh miner is recorded on Begonia.

A key to the European miners recorded on Begonia is provided in Bladmineerders van Europa.

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

1 > Leaf-miner: Large upper side blotch or blister mine, which can start with a short corridor. In small leaves the mine can be full depth in places. Often several larvae in a mine; frass irregularly scattered in large lumps. Pupation external.

The mine is illustrated in British Leafminers.

Large blotch, theoretically upper-surface, but often virtually full depth, often preceded by a short, broad corridor. Usually several larvae in a mine. The larvae can leave their mine and make a new one elsewhere. At the start of the first mine a small group of oval, whitish, egg shells. Pupation outside the mine.

On Fallopia, Persicaria, Polygonum, Rumex and possibly Begonia (record ambiguous) in Britain and in addition Begonia [Begoniaceae] and other genera of Polygonaceae elsewhere. Widespread in Britain. Also recorded in the Republic of Ireland. Widespread in continental Europe. Also recorded in Morocco, Algeria, Tunisia, Syria, Israel, Korea, China and Japan.

Pegomya bicolor (Wiedemann, 1817) [Diptera: Anthomyiidae].
