Identification
Broad, dark, postsutural transverse band on thorax, sometimes with edges indented, especially on female. Often with two small spots around anterior dorsocentral bristles. Scutellum darkened on approximately basal half, margin and tip gray. Hairs on arista much shorter than width of first flagellomere.
Range
e US, CA (TX-FL-MA-KS, CA) / Mex. to S. Amer. - Map (GBIF, BG data)
Native to Asia. Suwa (1987)(1) reviewing palaearctic Anthomyia gives distribution as "Japan; Korea; China; Oriental region." Griffiths did not mention the species in his 2001 revision of Nearctic Anthomyia and it was probably not widespread at that time, or not yet introduced.
Season
mostly: Apt-Oct (BG data)
Remarks
Presence of the Asian species Anthomyia illocata in North America has not been published. No North American species recorded by Griffiths(2) has a uniform transverse stripe on the mesonotum of the female. Of the species listed in the regional revisions of Ackland (1987, Oriental), Suwa (1987, east palaearctic), and Ackland (2001, Africa) none but A. illocata has the combination of nearly uniformly broad transverse stripe, two small spots over first dorsocentrals, and short hairs on arista. This species may have been introduced to Florida.
