Local Patch Reporter Richard Comont discovers an oil beetle. 

Species: oil beetle 

Location: Shotover Country Park

Date: 12 March 2014 

A slight diversion this week, and a step back in time to one of my former local patches. 

When I first moved to Oxfordshire, in 2008, I lived in Headington, north-east Oxford, and spent a lot of time in Shotover Country Park, then ably managed by Shotover Wildlife. 

I now live further away, in south Oxfordshire, but still visit Shotover from time to time to see black hairstreaks and other specialities.

Sunday evening was one such time. On my way home from Savernake forest, as it got dark, I decided to go and see if I could find any Minotaur beetles – nocturnal big, black horned dung beetles found in great profusion on Shotover.

Well, despite much searching, there were no minotaurs to be found.

What I did spot, in the light of a fading headtorch, was a great big bulbous black thing - an oil beetle! 

There used to be eight species of oil beetle (Meloe sp.) in Britain: three are now presumed extinct, two were thought to be extinct before being rediscovered in south Devon (and now survive in one and two sites respectively), two are widespread, if uncommon, and one is relatively widespread but even less common.

This one was relatively small, out at night, with a wide (not square) thorax and a groove in the middle of the pronotum – that made it Meloe rugosus, the rugged oil beetle! 

Not only was it a species I’d never seen before, despite looking, but really quite a rare species in Britain with only a handful of Oxfordshire records. 

When I got home I checked the records – one previous record from the site, in 1927, and astonishingly, in exactly the same 100x100m square!  After going missing for 87 years, the rugged oil beetle was back on Shotover… and it had barely moved an inch!

BBC Wildlife wanted to find a new way to share some of our readers’ natural-history diaries with other wildlife enthusiasts, and Local Patch Reporters was born. 

Our 20 Local Patch Reporters for 2014 are aged from 10 to 64 and live from Dorset in the south to Shetland in the north.

Throughout this year they will be exploring and reporting on nature in their neighbourhood via online blogs.

Richard Comont is a Local Patch Reporter from Oxfordshire.

“I’m interested in biological recording, particularly of invertebrates, and have recently started working for the Bumblebee Conservation Trust,” he says. 

Richard’s wildlife aims for 2014: Take part in the ‘1000 species in a 1km square’ challenge. I have my 1km square marked out around my house, but have set myself the challenge of finding 1000 species just in my house and garden.
