Description
Ophiomyia galiodes Lonsdale

Eiseman, mine on Galium asprellum (iNat 195125085); IOWA: Winneshiek Co., Decorah, Ice Cave Rd., 15.i.2021, J. van der Linden, mine with black puparium on Galium (BG 1931837); MASSACHUSETTS: Hampden Co., Monson, 42.061706, −72.275667, 5.x.2023, C.S. Eiseman, mine with black puparium on Galium mollugo (iNat 205101185); NEW YORK: Putnam Co., Kent, Huestis Town Park, 41.49236, −73.760266, 7.ix.2022, C.S. Eiseman, mine with black puparium on Galium mollugo (iNat 134116458); OHIO: Fairfield Co., Madison Twp., 39.600467, −82.661467, 23.xi.2023, C.S. Eiseman, mine with black puparium on Galium circaezans (iNat 191897579); VERMONT: Windham Co., 43.146319, −72.569864, 4.x.2025, C.S. Eiseman, larva mining Galium circaezans, formed black puparium by next day (iNat 323804641).
Hosts. Rubiaceae: [Galium asprellum Michx.], G. *boreale L., [G. circaezans Michx., G. mollugo L.] (Lonsdale 2021).
Larval biology. (Figs. 136, 137) The larva mines up and down the stem between two nodes, producing a grayish blotch that surrounds the stem, leaving the green core intact.
Puparium. (Fig. 32) Whitish; formed just beneath the stem epidermis, with the anterior spiracles protruding. The overwintering puparia we have seen were black, but they proved to be parasitized, so this may or may not be the normal color.
Phenology and voltinism. At least bivoltine, with pupae overwintering. The type series emerged from presumably overwintered puparia on 16 April in Maryland (Lonsdale 2021), and mines collected in Iowa from early July to late August yielded adults in late August. A larva presumed to represent this species was observed feeding on 4 October in Vermont, pupating by the next day.
Distribution. USA: [CT], *IA, [MA], MD, [NY, OH, VT] (Lonsdale 2021).
Comments. A male Brasema Cameron (Eupelmidae) (CSE7843, CNC) emerged on 14 or 15 September 2022 from one of the puparia collected in New York.
