Modern records
This species has suffered large declines since Jenyns’ day, and is now thought to be uncommon in Cambridgeshire, as opposed to being “found in plenty”. It is usually only seen in a few select locations across the county such as Devils Dyke and Barnack Hills and Holes, although records can pop up elsewhere.
