Calycomyza solidaginis (Kaltenbach, 1869)
Upper-surface primary blotch without clear primary or secondary feeding lines. The mine starts with a short corridor that generally is overrun by the later blotch. Colour yellowish-green to whitish. Rather little frass, fine-grained, brown (Hering, 1960a). The larva pupates in the mine, producing just before a large quantity of frass that dries and glues the puparium in the mine.

Erigeron acris; Solidago gigantea, virgaurea.
Larvae in June and September-October (Hering, 1957a).
