Hi Guy - I'm not sure what has resulted in this poor critter dragging her offspring around

... but the eggs look to be the correct shape to teh best of my knowledge. Large Skipper eggs aren't ribbed (I think that only applies to the Dingy and Grizzled skippers as far as British butterflies are concerned). The indented side of the otherwise-spherical egg is, presumably, where it should be attached to a blade of grass.
Cheers,
- Pete
