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).
