Species with which Red Sword-grass (Xylena vetusta) interacts

Grey Chi

I considered Grey Chi as well but I think that species would have an additional light line on the side which this does not show.

I could easily be wrong.

I had eliminated Red Swordgrass as the light green form is not figured in many of the sources I have (the darker form looks very different to this). But checking ukleps I think this looks like a good bet now.

Thanks for the suggestions. I am inclined to think it is the red sword grass caterpillar. Much appreciated.

Hi Idle lass and David, I

Hi Idle lass and David,

I noticed that the bright green version of RSG larva isnt very well represented in ukleps. This is the only version of it I have seen and Ive seen roughly 10 larva on moorland over the past 2 or 3 years. Ones I have seen as mature as this one were late July into early August.

It is a lovely caterpillar, quite amazing bright green.
