A surprise - everything is, if you've not seen it before.
Tracking down such things on the web needs selective words - Gall on Nettle brought the obvious (Puccinia urticata - see http://www.ispotnature.org/node/417828) but also the hint of another. Pasting Dasineura urticae into iSpot Search does it for me.
Further reading suggests - larvae causes a 'pouch' in leaf veins; absent from Orkney. (NBN). The pouches usually contained up to five little pale grubs - Picture 5 (added later)
