Found feeding on a gastropod in a river. Collected in South Africa.

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

Thank you very much, unfortunately I did not get a good photo of the head capsule

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!
