Male fly called "March Fly" or "Lovebug" in the USA. (Both unsuitable names here). Previously classified in the family Bibionidae but now segregated into the family Pleciidae. Probably Plecia dimidiata as this is the only one on the ALA in Victoria. Males have large heads and eyes.
Leaves fleshy, distinctly ribbed on the outside. Apex of mid-lobe of column (yellow part) somewhat dorsally compressed with a V-notch. Lateral lobes of column with a terminal tuft of white hairs, extending horizontally and converging. More than 5 flowers per stem (I can count 7 or 8 including the buds).
