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. |

and elsewhere and in addition Arctium, Homogyne and possibly Senecio elsewhere. Throughout the British Isles. Also recorded
