Caddisfly larva from a stream

It is difficuly to make much out of the larva but whilst I am happy it is Limnephilidae I am not happy it is Glyphotaelius as the larva looks too pale, the case is very untidy for a larva of Glyphotaelius at this size and it is late in the season and Glypho likes slow to still water.

I am not certain it is not Glyphotaelius and think that Limnephilus lunatus is more likely but alas microscope work is needed to be sure.
