Cecidomyia verbesinae Beutm.
1907 Beutenmueller, William. Amer. Mus. Nat. Hist. Bui. 23, p. 391
The galls are budlike, rounded, obtuse, usually unilocular or sometimes flattened and occur on the flower heads of Verbesina alternifolia. Polygnotus actinomeridis Ashm. MS (Insect Life 4: 126) was apparently reared from this gall.

One larva on slide taken from a polythalamous flower disc gall on Verbesina alternifolia (Linnaeus). One male and one female reared April 15 2012, from overwintering larvae. The gall is illustrated in Gagne on page 160 as Cecidomyia verbesinae. This species is clearly a Schizomyia, based on larvae and adults.
