Myopites tenellus (Frauenfeld, 1857)
the receptacle is sclerified and very strongly swollen upwards. Inside several vertical gall chambers, each with a maggot or a puparium. Each larva has arrived from an egg that was deposited on a flower, after which he has descended into the receptacle by way of a young achene; that achene is included in the galling process, and eventually functions as an exit channel for the fly. The galled achenes stand as cones upon the receptacle.
