Acidia cognata is one of the larger flies to make mines: the larva is about 12mm long. The mine is one of the few that start off as a narrow gallery and then suddenly convert to a blotch. Large flies demand large leaves, and these flies mine Coltsfoot. It's also interesting to note that Acidia belong to the Tephritid, or picture-wing flies. These usually eat seedheads of composite flowers, such as Knapweed and Thistles, so this foray into leaf-mining is quite a departure.
I've always wondered if Weeping Widow was named after the veil, but it turns out that the gills weep water when damp. Lacrymaria velutina.
I'm not 'doing' mosses at the moment: springtime is better for those. But I couldn't resist these Schistidium apocarpum capsules.
