My first thought is sawfly larvae of which, I gather, there are grass sawflies of the genus Pachynematus, [Hymenoptera, Tenthredinidae] - I know no more, or even whether there are European species (sorry, bit busy at the moment).
What is happening is even more confusing! Could be that one has failed to develope properly when shedding its skin? Or has it got a fungal infection? Sorry, no more ideas .....
