Parydra I imagine(?) following comparison with gallery images. If so, appears to key to P.quadrifasciatus in Drake 2006. - Yellow dusting on face. - No prominent tubercle on scutellum. - Appendix to wing vein. - Wing markings indistinct - Fan on front femora seems pale and about same length as narrowest width of femur itself. - Silver markings at base of mid-tibia Definitely on the larger side - perhaps 4mm or so? About twice the size of the other small Ephydrids I photographed there. e.g. https://www.inaturalist.org/observations/91509048 Shrewsbury river bank, UK - 16/08/21 sbushes attached the following image:  [139.56Kb] Edited by sbushes on 02-12-2021 20:02 |

no prominent tubercle on scutellum I believe, ruling out P.coarctata this image from one of the other flies, but the same business sbushes attached the following image:  [213.86Kb] Edited by sbushes on 17-08-2021 10:46 |
