Plant Parasites of Europe

leafminers, galls and fungi

Chromatomyia gentii

Chromatomyia gentii (Hendel, 1920)

mine

The mine begins as a short, narrow corridor running to the leaf tip. From there then descend some broad, sometimes branching, corriddors for about half the length of the leaf; locally they are almost full depth. Frass in large, loose, sometimes connected, grains. Pupation within the mine.

hostplants

Gentianaceae, monophagous

Gentiana acaulis, cruciata, lutea.

Whether the mine, described here really is the work of Ch. gentii was somewhat doubtful at the time of Hering (1957a) and this uncertainty has not been lifted since.

phenology

Larvae in July

distribution within Europe

Alpen.

synonyms

Napomyza gentii.
