Possibly the eggs of a bush-cricket. Both Roesel's Bush-cricket and the Long-winged Conehead are known to lay eggs in the stems of rushes.

I think that you could be on

I think that you could be on to something there, Michael. Benton (Grasshoppers & Crickets New Naturalist p.69) says that the eggs of bush crickets vary in shape according to ovipositor shape and where they are laid. "The eggs of the short-winged conehead, for example, are long and narrow, and inserted lengthways within the plant stem"

There are a couple of leaf miners it might be as well (though I favour the bush cricket theory).

1. An agromyzid fly Cerodontha luctuosa (NB this is found in the stem above the flower - so could be eliminated if these eggs were lower down)

2. A moth Elachista scirpi
