Is this a small mico-moth who's catterpillars feed on water weed?

Many thanks Dave, it does look as if it may be turnip sawfly (Athalia rosae) - it seems to have at least 6 pseudopods yet A. rosae apparently has 7 ..... but it's a bit tricky to tell from the photo.

See http://www.inra.fr/hyppz/IMAGES/7030842.jpg for a photo of turnip sawfly from INRA (http://www.inra.fr/hyppz/RAVAGEUR/6athros.htm)
