This is an image I caught on the old iPhone, not bad quality? Note the imaginatively named Swollen-thighed Beetle
There are also plenty of Cinnabar caterpillars feeding on the ragwort.
The final sighting of interest, although I didn't get a picture so can't be sure, but I'm fairly certain I saw a new hoverfly for me in the form of Helophilus trivittatus. This species looks superficially similar to the commoner H.pendulus with the thoracic stripes, but is larger, paler with a noticeably longer abdomen. Pretty sure it was one of these, but I'll try and get a picture all the same.
