another specimen


Small oval galls, c. 2 mm long, usually yellow or purple, on the stem or leaf, and then generally at the upperside of a thick vein. Larva solitary, dirty yellow. Several generations; the larvae of the summer generation pupate in the galls, the winter generation hibernates in the soil, then pupates.


Asteraceae, monophagous

Artemisia abrotanum, montana, princeps, vulgaris.

Rhopalomyia foliorum: prosternum

the prosternum has no spatula (from Möhn, 1955a). See also Ganaha ao.


Diarthronomyia foliorum.


Rh. foliorum is known exclusively from Artemisia; a comparable gall on Achillea is not known. Because of the relatively close relationship between the two genera, the galls on Achillea ptarmica depicted above are provisionally iddentified as cf. Rh. foliorum.
