Melanagromyza buccalis Spencer

(Fig. 7)

Material examined. MASSACHUSETTS: Franklin Co., Northfield, 276 Old Wendell Rd., 20.viii.2016, mating on Erigeron annuus, #CSE2916, CNC654071, CNC654072 (1♂ 1♀).

Hosts. A California specimen was reared from an unspecified legume ( Fabaceae) (Shi & Gaimari 2015). Several collection records suggest an association with Asteraceae, beyond the pair we found mating on a receptacle of Erigeron annuus (L.) Pers. (Fig. 7). A long series was caught on Salix eastwoodiae Cockerell ex A. Heller (Salicaceae) but believed to be associated with Arnica L. growing beneath the willow trees (Spencer 1981). Other California specimens have been collected on “ Chrysanthemum ” and Dahlia Cav. (Asteraceae), as well as on an unspecified Salix, Hydrangea L. ( Hydrangeaceae), Rosa L. ( Rosaceae) and Citrus L. ( Rutaceae) (Shi & Gaimari 2015).

Larval biology. Unknown; most Melanagromyza species are stem borers, with others feeding in seedheads.

Distribution. USA: AZ, CA, CO, *MA, MD, MO, NY, VA; Canada: ON, QC (Shi & Gaimari 2015).
