One of my best jobs this year has been a four-day survey of Orford Ness for the National Trust under an EU LIFE programme. The main aim of the survey was to survey invertebrates in and around saline and brackish lagoons, including some which have recently been created as well as some older examples.
I’d never been to Orford Ness before and I was soon wondering why on earth not. The range of habitats is excellent, including some amazingly natural and undisturbed transitions from saltmarsh through to shingle. And although there’s a good list of invertebrates for the site, it still feels massively under-worked for somewhere that is clearly a nationally important site for invertebrates. Despite some dreadful weather in late June, I kept hard at it in the hope of making some good discoveries.
This was the best spot on the whole survey. There were several Saltmarsh Shortspurs Anisodactylus poeciloides under the wood when I turned it over, scattering in all directions. Grubbing about at the roots of the Marsh Foxtail, I also found a single Great Trident Sunshiner Amara strenua.
Thinking that this was a very good spot indeed, I looked harder still and spotted a tiny (1 mm), globular, shiny, black insect. It could have been a mite but it moved like a beetle so I got a lens on it and realised it was an Orthoperus (Corylophidae). I managed to get it safely into a pot along with a second individual but couldn’t find any more despite an hour spent searching within the red ring above. I was instantly hopeful that an Orthoperus in such habitat might turn out to be O. brunnipes, a Rare (RDB3) species that I had attempted to find at Murston Marshes, north Kent only three weeks earlier. On that occasion, not only did I fail to find O. brunnipes but I found a large new industrial estate on the site, and after searching around the remnant bits of marsh, returned to find I’d got my car locked in for the night. So to bump into it unexpectedly on Orford Ness was a real highlight for me. Also here was my first Peritrechus nubilus (a ground bug). Corylophidae once seemed such an impossibly difficult family to me, so it is encouraging to know that I have now found all the British species except for O. atomarius, the one that usually occurs in wine cellars. Now if anyone knows of a wine cellar that I could poke about in, preferably with plenty of mouldy old wine casks, do get in touch!
