Chloropidae: Tricimba humeralis (Loew, 1858) and in numbers Trachysiphonella ruficeps (Macquart, 1835). Nice photo! The flies (documented in the literature predominantly females) are kleptoparasites and feed on the pre-orally digested mirid and its haemolymph which they use as food and probably as a repellent for themselves or their eggs.
