Hi dipterists
Found and observed on the water surface of a pond
covered by Lemnaceae (Lemna minor)
This larva is 15-20 mm length and as I try to leave save all observed larvae
the pictures are not so easy to be high-definition quality
Oxycera calceata ? previously Hermione

Thanks for confirmation





air fringe on the terminal segment



spiracles on the first thoracic segment sides



2 hooks on the ventral last abdominal sgement




ventral view of the mandibles and mouth parts



Head dorsal view


A last question
Are they 2 GILLS, those white clouds on either side of the head ???

merci beaucoup
