Very common yesterday on Upright Hedge Parsley at edge of coniferous rides.
No interactions present.
Having gone through my specimens from this visit, I am not sure that I can be certain these are all clunipes. They probably are, as I tried to keep tabs on photos = specimens, but I did have a few specimens of S. elegans and S. verecunda, as well, and they could have crept in here!
