(Coleoptera, Diptera, Hymenoptera and Lepidoptera)

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


HOMOGYNE. Purple Colt's-foot. [Asteraceae]

Only one species of Homogyne is recorded in Britain, the introduced Purple Colt's-foot (H. alpina).

Only one British miner is recorded on Homogyne.

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

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

1 > Leaf-miner: An upper surface corridor mine, becoming strongly broadened and blotch-like. The mine can occupy a considerable part of a small leaf. Mines frequently merge and then accommodate several larvae. Pupation external, in the soil.

Upper-surface corridor, in the end strongly widened and blotchy; may occupy a large portion of smaller leaves. Mines may coalesce, and contain several larvae then. Primary and secondary feeding lines very conspicuous (picture). Pupation outside the mine.

Makes upper surface blotches.

On Petasites, Tussilago and possibly Senecio, but not yet on Homogyne, in Britain and elsewhere and in addition Arctium, Homogyne and possibly Senecio elsewhere. Throughout the British Isles. Also recorded in the Republic of Ireland and Widespread in continental Europe.

Acidia cognata (Wiedemann, 1817) [Diptera: Tephritidae].
