On investigation and discussion with T Irwin it appears this is some form of biting Midge larvae in the genus Formicopyia.

from TI

Your photos do show a Forcipomyia larva. The blunt-tipped bristles on the back produce a hygroscopic substance that causes water droplets to form.
These then run down onto the larva, keeping it damp and enabling it to breathe easily. Forcipomyia larvae the world over share the same trick.
Several species have been described as larvae, but I don't have the article, and in any case, I'd be hesitant to say which species this is,
when some of the species are still unknown in the immature stages.

Notes from JM on Zygodon id

Your photos are very clear and the measurements are what is required - measurements of more gemmae (say 5-10) would be good
to get more of a picture and also some of the leaf features (see following).  However, as I conclude - it is most likely Z. viridissimus.

In order to fully key out Zygodon (I have used Smith p 659) - some of the leaf features are needed for full determination:

toothing towards apex of leaf present / or not
lf cells papillose / or not
mid leaf cell width
costa excurrent/ or not

This would enable a check for gracilis, forsteri or stirtonii  (of which Z. stirtonii is an outside possibility as found very rarely in Norfolk. The other 2 are very localised). F
or example,  Z. stirtonii found at Stratton Strawless churchyard in 2008 by Norfolk Bryology Group.  Latest record 2018 at Roughton again in a churchyard.  Only 21 records for Norfolk on NBN.

Then you get to Z. conoideus which has gemmae 7-8 cells long and without longitudinal cell walls (plus cell width on mid leaf required).

So from your photos I would say it is not Z. conoideus.

Then Z. viridissimus - versus - Z. rupestris.  These are separated on gemmae width, and presence of longitudinal cell walls present (sometimes in
viridissimus or not at all in rupestris).  Your widths are 32 and 34 and one has a longitudinal wall.   So on balance therefore I'd say Z. viridissimus.
