Ophiomyia beckeri (Hendel)

( Figs. 5 , 29 )

Material examined. NORTH CAROLINA : Durham Co., Durham , Pelham Road, 13.vi.2015, em. 16.vi.2015, T.S. Feldman, ex Sonchus , # CSE1619 , CNC564619 (1♂); Durham , 17.vii.2015, em. by 3.viii.2015, T.S. Feldman, ex Sonchus ?asper , # CSE2120 , CNC564631 (1♂); Scotland Co. , Laurinburg, St. Andrews University, 10.iv.2017, em. 16–18.v.2017, T.S. Feldman, ex Krigia virginica , # CSE3677 , CNC939735 , CNC939736 (2♂) .

Hosts. Asteraceae : * Krigia virginica (L.) Willd., Sonchus L.

Leaf mine. ( Fig. 29 ) Larva primarily boring in the leaf midrib, making short corridors into the blade and sometimes overlying the midrib. The branches are virtually free of frass, which accumulates in the larva’s resting place at the base of the midrib ( Ellis 2018).

Puparium. Yellowish-white or sometimes black, formed in the base of the midrib ( Ellis 2018).

Distribution. * USA: NC; Africa; Asia; Europe.

Comments. This is the first record of any agromyzid from Krigia Schreb. TSF has also found an undetermined species of Liriomyza Mik mining leaves of K. virginica at St. Andrews University.
