Plant Parasites of Europe

leafminers, galls and fungi


Amsinckia fiddleneck

Dichotomous table for leafminers

1a large brown blotch: cf. Agromyza abiens

1b galls, etc => Tables for all parasites per species

Steven IJland sent me dried material that he had collected near the Hague in mid May. The mine was a brown blotch of ca. 4 cm without a visible trace of an initial corridor. This suggests A. abiens or A. ferruginosa, but the relatively small size agrees most with abiens. However, Boraginaceae harbour a rich agromyzid fauna, and without larvae a definite identification is not possible.

The observation nevertheless is interesting because in the literature Amsinckia is not mentioned as a host to miners, let alone to Agromyzidae. The genus originally occurs in North America, but even the manual of US Agromyzidae by Spencer & Steyskal (1986a) does not mention the genus.
