Thought it might be but wasn’t confident enough to go to species level, also thought it was more of a wet grassland species.
Yes this is C. grossa - you can see the orange hind tibiae plus the black antennae. Only other species it might be at this time of year have dark rings on legs. (however you cannot use this rule!)
Thanks for the ID and comments.
