Roesel's Bush Baby?

So pleased that the saltatorians are back. :) I spent my birthday afternoon yesterday rolling around in wet grass capturing crickets and grasshoppers. I couldn't wait to go hunting again today. My pic is of the tiniest cricket nymph that I have ever captured. I think it must be a first instar. I have a feeling that it might be a Roesels's bush cricket as it has that creamy line round the thorax, even though its antennae are white and its body light. The adults have dark antennae and bodies. I've included a pic in extras of it with a vetch flower to show how tiny it is.
