Is this rather far north for this species, I thought they tended to be further south?
No interactions present.
There are previous records for Dry Sandford Pit, and they do go further north, see the NBN map on the recording scheme page:
(scroll down for map)
In my experience they have a curiously fragmented distribution, and don't disperse to new sites often, but populations do seem to be reasonably stable at the sites I know.
Always a fantastic creature to see, they seem too big to be a British insect!
