 Looks very similar to our European larvae of Notiphila or Hydrellia. Both piercing waterplants with their anal spines which are connected with the trachea. A detailed photo of the mandibles or head capsule would help in determining the genus

 Behaviour sounds more like Sciomyzidae. Any particular reasons for it not to be a sciomyzid?

 It has a piercing posterior spine (in fact 2 close together), seen at top right. No such spine in any Sciomyzidae. I have seen this too many times..

 It makes sense when you look at it that way round! Shock
I should have realized that, given my avatar!

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
